DNA/RNA

Note

Member of the Selectin family. ELAM and CD62E, two of the alternative gene names, have continued to be used in the literature for this gene.

Description

This gene can be found on Chromosome 1 at location 167,958,406-167,969,803. The gene is composed of 14 exons, spanning approximately 12 kb of genomic DNA in the telomere-to-centromere orientation on chromosome region 1q22-1q25. The promoter region is not included.

Transcription

NM_000450 3834 bp mRNA. The sequence is supported by several sequences (cDNA clones) and produces, by alternative splicing, 5 different protein isoforms (6 transcripts). The transcripts differ by truncation of the N-terminus, truncation of the C-terminus, presence or absence of an exon.

None

Proteins

Atlas Image

Description

Selectin E precursor is composed of 610 amino acids (66655 Da). Subcellular location: Membrane; Single-pass type I membrane protein. It exhibits structural features such as the presence of lectin- and EGF-like domains followed by short consensus repeat (SCR) domains that contain 6 conserved cysteine residues (Sushi domains). E-Selectin belongs to the selectin family of proteins. Amino acids: 610; Molecular Weight: 66655 Dalton. The phosphorylation on Tyr-603 (cytoplasmic domain) is required for the E-selectin-dependent ERK1 / ERK2 activation.

Expression

The endothelial leukocyte adhesion molecule-1 is ubiquitously expressed in normal tissues. SELE is expressed at high level in cytokine-stimulated endothelial cells.

Localisation

Single-pass type I membrane protein.

Function

E-Selectin is thought to be responsible for the accumulation of blood leukocytes at sites of inflammation by mediating the adhesion of cells to the vascular lining. Adhesion molecules participate in the interaction between leukocytes and the endothelium and appear to be involved in the pathogenesis of atherosclerosis.

Homology

Using pairwise alignment function of ClustalW2, the corresponding sequences from Mus musculus and Rattus norvegicus match with a score of 72 and 73 respectively.

Mutations

Note

Since adhesion molecules such as members of the selectin family participate in the interaction between leukocytes and the endothelium and appear to be involved in the pathogenesis of atherosclerosis, Wenzel et al. (1994) sought DNA polymorphisms in the ELAM1 gene, which appears to be expressed only in activated endothelium. They identified an A-to-C transversion at cDNA nucleotide 561, resulting in an amino acid exchange from serine to arginine at codon 128 (S128R) in the epidermal growth factor-like domain. They found a significantly higher frequency of the mutation in 97 patients aged 50 years or less with angiographically proven severe atherosclerosis (arginine allele frequency, 0.155) compared with an unselected population (arginine allele frequency, 0.088), as well as in 40 patients aged 40 years or less (arginine allele frequency, 0.21). Mutations of the gene may be a risk factor in atherosclerosis. A polymorphism in position 149 is associated with a higher risk of coronary artery disease (CAD). A significantly higher mutation frequency (Arg-149) is observed in patients with angiographically proven severe atherosclerosis compared with an unselected population (Ser-149).Genomewide linkage and candidate gene-based association studies demonstrated that variation in 3 genes on 1q23 is important in the determination of differences in blood pressure levels: ATP1B1 (182330), RGS5 (603276), and SELE (Takei et al, 2002; 131210). E-selectin S128R polymorphism can functionally affect tumor-endothelial interactions as well as motility and signaling properties of neoplastic cells that may modulate the metastatic phenotype (Alessandro et al, 2007).

Implicated in

Entity name
Recruiting blood leukocytes to the site of inflammation
Note
E-selectin plays an important role in recruiting leukocytes to the site of inflammation. E-selectin is expressed on endothelial cells in response to inflammatory cytokines IL-1 and TNF-alpha (Bevilacqua et al., 1989). Leukocytes in the blood expressing the correct ligand will bind with low affinity to E-selectin, causing the leukocytes to "roll" along the internal surface of the blood vessel as temporary interactions are made and broken. For these reasons the protein encoded by this gene is thought to be responsible for the accumulation of blood leukocytes at sites of inflammation by mediating the adhesion of cells to the vascular lining.
Entity name
Coronary artery disease
Note
Risk of acquiring coronary artery disease in patients with type 2 diabetes mellitus increases significantly in the presence of the 128R mutant allele of the E-selectin gene (Abu Amero et al., 2007). Other authors correlated the G98T mutation in the E-selectin gene with a higher risk of premature coronary artery disease (Zheng et al., 2001). Data from other laboratories confirmed the hypothesis that in systemic inflammation altered E-selectin shedding may play a role in arterial damage and implicated this adhesion molecule in atherosclerotic complications in a high-risk condition (Malatino et al., 2007)
Entity name
Colon carcinoma
Note
Transendothelial migration of colon carcinoma cells
Oncogenesis
E-selectin mediates the adhesion of tumor cells to endothelial cells, and this interaction is associated with metastatic dissemination. Alessandro et al.(2007) studied the S128R polymorphism in the E-selectin gene in patients with metastatic colon cancer and its functional significance. Genotyping for S128R polymorphism was performed on 172 cancer patients and on an age-matched control population demonstrated that the R128 allele was more prevalent in the metastatic patients group than in the non metastatic group or normal controls. In vitro, S128R E-selectin transfected Huvec cells, supported increased adhesion as well as increased cellular signalling of T84 cancer cells compared to WT E-selectin and mock transfected Huvec cells. These findings suggest that the E-selectin S128R polymorphism can functionally affect tumor-endothelial interactions as well as motility and signaling properties of neoplastic cells. These interactions may ultimately modulate the metastatic phenotype.
Entity name
Angiogenesis
Note
E-selectin plays an important role in endostatin-mediated antiangiogenesis. E-selectin is required for the antiangiogenic activity of endostatin in vivo and ex vivo, and is sufficient, via a mechanism requiring the E-selectin cytoplasmic domain, to confer endostatin sensitivity in endothelial cells in vitro (Yu et al., 2004).
