DNA/RNA

 
  Diagrammatic representation of human ENAH gene trancripts. Exons are enumerated and the relative protein domains are indicated.
Description The human ENAH gene is located on the minus strand of chromosome 1 and is constituted by 15 exons. Other features of the ENAH gene such as promoter or enhancer have not been fully investigated.
Transcription Two alternative splice variants isolated in the human ENAH. The size of the longer variant (hMena+11a or ENAH variant 1) is 1776 nt. The shorter variant (hMena or ENAH variant 2) lacks an internal exon (exon 11a) of 63nt.

Protein

 
  Human ENAH protein, the four conserved domains are indicated with the respective amino acid positions. The 11a peptide is included at position 513 and characterizes the ENAH isoform a (hMena+11a).
Description Mena is a member of Ena/VASP proteins characterized by the presence of specific domains including the NH2-terminal EVH1 domain, which plays a role in intracellular protein localization (Prehoda et al., 1999) and interacts with proteins bearing FPPPP motifs. Among the Ena/VASP proteins only the EVH1 domain of Mena possesses the ability to bind to the LIM3 domain of the oncosuppressor TES (Boeda et al., 2007). The central proline-rich domain mediates the interaction with proteins containing the SH3 and WW domains and with the small actin monomer binding protein profilin (Gertler et al., 1996). The LERER region is constituted by a long repeat of Arg/Leu/Glu amino acids probably acting as a protein protein binding interface, located between the EVH1 and the prol-rich region. Only Mena among the Ena/VASP proteins possesses this domain. The EVH2 COOH-terminal domain, which forms a right handed alpha helical coiled coil structure, is responsible for tetramerization and for the binding to G- and F-actin (Kuhnel et al., 2004); its interaction with the growing ends of the actin filaments is required for targeting the Ena/VASP to lamellipodia and filopodia (Louriero et al., 2002). Human Mena (hMena or ENAH isoform b) is a 570 amino acid protein. The longer hMena+11a isoform (ENAH isoform a) presents an additional internal peptide of 21aa located in the EVH2 domain of the protein. This isoform undergoes phosphorylation upon treatment of breast cancer cell lines with EGF and NRG1 (Di Modugno et al., 2007).
Mena is alternately spliced to give rise to multiple isoforms, an additional reported isoform is the neuronal specific Mena-140 found in mouse and humans (Gertler et al., 1996; Urbanelli et al., 2006).
Expression In normal tissues, hMena expression was confined to isolated epithelia (i.e.pancreas). Mammary epithelium was negative and hMena was overexpressed in about 75% of breast primary tumors tested, with a variable staining intensity.
Localisation Predominantly in cytoplasm and in some tumor cells with a reinforced juxtamembrane staining.
Function Mena controls cell shape and movement (Bear et al., 2002; Vasioukhin et al., 2000; Krause et al., 2003) by protecting actin filaments from capping proteins at their barbed ends (Barzik et al., 2005). It controls actin organization on cadherin adhesion contact (Scott et al., 2006).
Homology The sequence of hMena (ENAH isoform b) displays 87% identity with the murine protein but is longer with the majority of the additional aminoacids located in the Arg/Leu/Glu rich region (LERER). The human hMena sequence conserved the two serine phosphorylation sites of murine Mena, whereas the tyrosine residue, site of phosphorylation in mouse Mena (Tani et al., 2003), is substituted by a glutamine residue in the human sequence.

Note
  
Entity Breast Cancer
Disease In human tissues, human ENAH (hMena) protein, not expressed in normal breast, is detectable in a small percentage of low-risk proliferative lesions, with a progressive increase of positivity in benign breast lesions at higher risk of transformation and in in situ and invasive cancers. In the latter, a significant direct correlation was found between hMena, tumor size, proliferation index, and HER-2 overexpression whereas an inverse relationship was evidenced with estrogen receptor (ER) and progesterone receptor (PgR) expression (Di Modugno et al., 2006).
These results suggest that hMena may be a marker of breast cancerogenesis and breast cancer progression.
In cancer cell lines of different histological origin, hMena is overexpressed respect to the normal counterparts (i.e. breast, melanoma, colon, cervical cancer). hMena expression while up-regulated by Neuregulin-1 and EGF, is down-regulated by Herceptin treatment in breast cancer cell lines, thus suggesting that hMena couples tyrosine kinase receptor (TKR) signaling to the actin cytoskeleton.
hMena+11a isoform (ENAH isoform a) is epithelial-specific and is phosphorylated after mitogenic stimuli, such as EGF. This phosphorylation is accompanied by an increased proliferation rate and p42 / 44 MAPK activation in breast cancer cell lines (Di Modugno et al., 2007), thus suggesting a functional role of hMena+11a in breast cancer cell proliferation. In a murine model Mena is overexpressed, among a set of genes coding for the minimum motility machine regulating β-actin polymerization, in a subpopulation of invasive breast tumor cells collected using the in vivo invasion assay in response to EGF (Wang et al., 2004). A role of hMena in the invasive behaviour of human tumor cells has not yet been reported.
  
  
Entity Pancreatic Cancer
Disease hMena is expressed in primary and metastatic pancreatic cancer. The expression of hMena+11a isoform (ENAH isoform a) characterizes pancreatic cancer cell lines with an epithelial phenotype which express the epithelial marker E-Cadherin and lack the expression of mesenchymal markers as N-Cadherin and Vimentin. These cell lines show a constitutive activated EGFR and are sensitive to the treatment with the EGFR inhibitor Erlotinib. ENAH acts as a mediator of the EGFR signaling pathway and significantly modulates the growth of pancreatic cancer cell lines dependent on EGFR signaling. Thus the expression of hMena/hMena+11a is predictive of in vitro response to EGFR inhibitors (Simo et al., 2008).
  
  
Entity Tumor Immunity
Disease Human ENAH (hMena) protein is able to induce a cancer-restricted antibody response. Twenty percent of cancer patient sera, showed anti-hMena-specific IgG, while no antibodies were present in healthy donors (Di Modugno et al., 2004).
