Note EPHA2 was identified in 1990 by the screening of human epithelial cells (HeLa cells) cDNA library using degenerate probes designed to hybridize to highly conserved regions of protein tyrosine kinases. EPHA2 was initially referred to as Eck (epithelial cell kinase) for its expression in the majority of epithelial cells.

Protein

 
  Structure of EPHA2 protein.
Description EPHA2 receptor is a transmembrane glycoprotein composed of 976 amino acid residues, with a calculated molecular mass of 130 kDa and an isoelectric point 6.1398. It is one member of the largest EPH (erythropoietin-producing hepatoma amplified sequence) family receptor tyrosine kinases. The family of Eph kinases binds ligands (known as ephrins) that are anchored to the membrane adjacent cells and consists of 16 known members across species, 14 of which are found in mammals and characterized by shared features in both the extracellular and intracellular domains.
EPH class receptors contain a single transmembrane spanning domain. Like other receptor tyrosine kinases, the extracellular domain of EPHA2 mediates ligand binding whereas the intacellular domain possesses intrinsic enzymatic activity.
The extracellular domain is glycosylated and is composed of globular, amino terminal domain followed by a cysteine-rich region with an epidermal growth factor-like motif and two fibronectin III-type repeats. The globular, amino-terminal domain contains immunoglobulin-like motifs and is both necessary and sufficient for ephrin-binding.
The intracellular domain includes a juxtamembrane region, a tyrosine kinase domain, a sterile alpha motif (SAM) and a PDZ-binding motif in the carboxy terminal end. The kinase domain and juxtamembrane region contain tyrosine residues and phosphorylation of these tyrosine residues creates docking sites for interaction with signalling proteins containing SH2/SH3 (Src - homology - 2/3) domains. SAM domain forms homodimers and may regulate receptor dimerization. The PDZ-binding motif binds to PDZ domain-containing proteins, which are though to serve as scaffolds for the assembly of multi-protein signalling complexes at the membrane.
EPHA2 shows 25-35% sequence homologies with other EPH receptors, and the tyrosine residues are conserved within the juxtamembrane and kinase domain.
Expression EPHA2 is largely restricted at low levels on adult proliferating epithelial cells and enriched within sites of cell-cell adhesion in normal epithelial cells. EPHA2 expression has been detected in the brain, skin, bone marrow, lung, thymus, small intestine, colon, urinary bladder, kidney, liver, spleen, uterus, testis and prostate. EPHA2 expression levels in the colon, skin, kidney and lung were over 10-fold compared to those of the bone marrow. EPHA2 is also expressed during gastrulation in the ectodermal cells and early embryogenesis in the developing hind brain. In the skin, EphA2 is present in keratinocytes of epidermis and hair follicles but not in dermal cells, such as fibroblasts, vascular cells and inflammatory cells. EPHA2 has also been detected in proliferating mammary glands in female mice at puberty and differentially expressed during the estrous cycle. EPHA2 is widely unregulated and functionally altered in a variety of carcinomas and is implicated in cell transformation, primary tumor initiation, angiogenesis and metastasis in advanced cancer models. Overexpression has been shown both at the mRNA and protein level in established cell lines and human clinical specimens. Consistent findings indicate the prevalence of EPHA2 overexpression in many cancers, including glioblastoma, colorectal, gastric, esophageal, breast, thyroid, ovarian, endometrial, cervical, pancreatic, prostate, melanoma, bladder, renal cell, lung and hepatocellular carcinoma.
Localisation The EPHA2 is localized to the cell membrane.
Function The ligands for the EPH receptors are ephrins, which are 9 members and also fall into 2 subclasses: the GPI (glycosylphosphatidylinositol) anchored A-class of ligands (Ephrin A1-6) and the transmembrane B-class of ligands (B1-3).
EPH receptors interact with their cognate membrane anchored ligands at cell-cell contact sites to activate bidirectional signaling pathways effecting diverse physiologic processes including cell adhesion, repulsion, morphology, migration, differentiation and proliferation. Specifically, EPHA2 is activated by the ligand ephrin A1/EFNA1 and regulates migration, proliferation, integrin-mediated adhesion and differentiation of cells.
EPH receptor signaling has been implicated in many biological processes such as axon guidance and fasciculation, tissue border formation, neuronal targeting and angiogenesis during embryonic development. Especially, EPHA2 is involved in angiogenesis, in early hindbrain development and epithelial proliferation and branching morphogenesis during mammary gland development. EPHA2 with ephrin A2/EFNA2 may play a role in bone remodeling through regulation of osteoclastogenesis and osteoblastogenesis. It also engaged with the ephrin A5/EFNA5 and may regulate lens fiber cells shape and interactions and be critical for lens transparency development and maintenance.
Emerging evidence implicates EPHA2 overexpression in cell transformation, primary tumor initiation, progression, angiogenesis and metastasis in a variety of cancer models.
Homology Human EPHA2 shares 96% amino acid identity with the chimpanzee, 95% amino acid identity with dogs, 94% with cows, 93% with mouse, 92% with rats and 56% amino acid identity with zebrafish.

Mutations

Note Congenital cataract (CC) is one of the most significant causes of visual impairment and blidness in childhood. Approximately, up to 25% of all CC could be inherited, most often transmitting as an autosomal dominant trait and showing considerable inter- and intra-familial phenotypic variation.
Germinal Loci for autosomal dominant posterior polar CC and total CC have both been mapped to chromosom 1p36 harboring the EPHA2 gene. Two missense mutations and one frameshift in the EPHA2 gene have been linked with posterior polar CC and one splicing mutation have been associated with total CC.
The c.2819 C>T (p.T940I) missense mutation changes an oligomerization interface of the SAM domain, most likely inactivating the EPHA2 signalling function by destroying its SAM domain.
The c.2842 G>T (p.G648W) missense mutation identified in exon 17 and occured at the first base of codon 948 and was predicted to result in substitution of glycine to tryptophan at the level of translation, placing it in the cytoplasmic SAM domain of EPHA2 gene.
The c.2915_2916delTG deletion of 2 bp discovered in exon 7 of EPHA2 gene and was predicted to result in a frameshift mutation creating a mutant protein with a novel C-terminal polypeptide of 39 amino acid residues.
The c.2826-9G>A is a splicing mutation with a single base substitution in intron 16 which creates a novel splice acceptor site causing an intronic sequence of 7 bp to be included in the processed transcript. This aberrant splicing is predicted to result in translational of a novel C-terminal polypeptide of 71 amino acid residues of which the last 39 are identical to that of the nove polypeptide produced bt the c.2915_2916delTG.

Implicated in

Note
  
Entity Various cancers
Note EphA2 has been reported to be overexpressed in several cancers and a high level of EphA2 has been detected in malignant cancer-derived cell lines and advanced forms of cancer.
Prognosis Eph-A2 overexpression was significantly associated with poor prognosis in several types of malignant tumors, including oral tongue, oesophageal, lung, renal, ovarian, cervical and endometrial carcinoma, as well as glioblastoma and melanoma. In human epidermal growth factor receptor 2 (Her2) positive breast cancer patients, increased levels of EphA2 mRNA were correlated to a decreased potential for overall and disease-free survival.
  
  
Entity Epithelial ovarian carcinoma
Note High EphA2 expression was evident in clinical specimens of invasive ovarian tumors, while little or no staining was observed in normal ovaries. Moreover, EphA2 overexpression was significantly associated with higher grade, advanced disease stage and with factors involved in invasion and angiogenesis. A relationship between EphA2 overexpression and the status of tumor suppressor p53 was noted. High EphA2 expressing tumors exhibited increased microvessel density when stained for CD31 as a measure of angiogenesis. In addition, the matrix metalloproteinase expression, which degrades the extracellular matrix during cancer progression, was also associated with EphA2 expression.
  
  
Entity Prostate cancer
Note In clinical prostate carcinoma specimens, EphA2 immunoreactivity was increased with a positive staining in 60-100% of cells. EphA2 was overexpressed more in metastatic cells compared to non-invasive prostatic epithelial cells and its levels as increased as prostatic epithelial cells moved toward a more aggressive phenotype.
  
  
Entity Breast cancer
Note In breast carcinoma specimens, 92% of the cases showed moderate to high staining for EphA2. EphA2 overexpression in breast cancer was negatively associated with estrogen receptor expression. In clinical specimens of benign mammary epithelia, 75% of the specimens were negative, while 25% were weak positive.
  
  
Entity Pancreatic carcinoma
Note EphA2 was overexpressed in about 95% of pancreatic cancer specimens, being associated with metastatic disease, increased cellular invasiveness and patients' age.
  
  
Entity Lung cancers
Note In non-small cell lung cancer specimens, moderate to high EphA2 immunostaining was observed in the membrane and cytoplasm in more than 70% of the examined carcinomas. This increase was comparable in adenocarcinoma, squamous cell carcinoma and large cell carcinomas. EphA2 was also associated with clinically advanced stages of disease, the presence of brain metastasis and smoking status.
  
  
Entity Brain cancers
Note EphA2 was found to be overexpressed but not to be tyrosine phosphorylated in glioblastoma multiforme cells or tumors. In surgically resected human malignant glioma tissues, a heterogeneous and variable EphA2 staining pattern was observed. Although normal brain tissues exhibited minimal EphA2 staining, the cases of anaplastic astrocytoma and glioblastoma multiforme exhibited variable staining patterns. In astrocytic tumors, EphA2 overexpression was also correlated with the pathological grade and the proliferation status of tumors.
  
  
Entity Urinary bladder carcinoma
Note Clinical specimens of urinary bladder carcinoma when examined by a semi-quantitative immunostaining showed a differential staining pattern than normal specimens. Of all urinary bladder specimens with Ta grade lesions, 30% showed moderately strong staining, while in the T3 and T4 lesions, 75% and 90% of the samples showed strong staining, respectively. In sharp contrast, 85% of normal tissues showed weak staining, while the remaining 15% showed moderate staining for EphA2. Notably, EphA2 staining intensity was associated with advanced stage of urothelial carcinoma.
  
  
Entity Melanoma
Note EphA2 was found to be phosphorylated in aggressive melanoma-derived cells and was associated with vasculogenic mimicry, i.e. the formation of endothelial cell-like network. In a tissue microarray of melanomas, strong cytoplasmic EphA2 staining was present in 16% of the cases, being associated with histological thickness of melanomas and tumors proliferation status. A correlation of metastatic potential and high EphA2 expression was also observed in human melanoma cell lines derived from patients, while EphA2 overexpression changed cellular migration from the mesenchymal- to the amoeboid-type.
  
  
Entity Oesophageal squamous cell carcinoma
Note EphA2 overexpression was detected in esophageal carcinoma-derived cells and in 50% of clinical specimens. EphA2 expression was correlated with lymph node metastases, whereas no significant association with patients' age, tumour location, tumour size, histological differentiation and clinical stage was noted.
  
  
Entity Colorectal carcinoma
Note Increased expression of EphA2 was observed in over 59% of clinical specimens from colorectal cancer patients. EphA2 expression was increased in early-stage tumors compared to those of advanced stage, as well as in smaller tumors than large tumors. Microvessel count was also correlated with overexpression of EphA2. In human colon cancer-derived HCT116 cells, a dose and time-dependent upregulation of EphA2 was noticed after treatment with deoxycholic acid, a component of bile acids and promoter of colon cancer. The upregulation of EphA2 was p53-independent, but it was linked to the activation of MAP kinase pathway.
  
  
Entity Renal cell carcinoma
Note Higher levels of EphA2 expression were correlated with tumors that were of higher grade, larger and more highly vascularized in patients with renal cell carcinoma.
  
  
Entity Vulvar carcinoma
Note In vulvar cancers, more than 50% of vulvar squamous cell carcinomas expressed elevated levels of EphA2.
  
  
Entity Malignant and benign thyroid malignancies
Note Eph-A2 receptor was associated with increased proliferative activity of malignant thyroid lesions. Eph-A2 was significantly overexpressed in malignant compared to benign thyroid lesions. Papillary carcinoma cases also presented significantly increased Eph-A2 expression compared to those with hyperplasia nodules.
  
  
Entity Squamous cell cervical carcinomas
Note In early squamous cell cervical carcinomas, EphA2 expression was classified as negative in 21 tumors (10%), weak positive in 108 tumors (50%), moderate positive in 69 (32%) and strong positive in 19 tumors (9%).
  
  
Entity Oral tongue squamous cell carcinoma
Note In oral tongue SCC specimens, Eph-A2 expression was significantly correlated with tumor size, clinical stage, lymph invasion, recurrence and distant metastasis.
