Description de la cible

Protein enabled homolog (UniProt: A0A097PIC4; also known as hMENA, Mammalian enabled variant 11a, ENAH) is encoded by the ENAH (also known as MENA) gene (Gene ID: 55740) in human. hMENA is a homotetrameric actin regulatory protein of the ENA/VASP family that plays a key role in cell processes that rely on actin cytoskeleton dynamics. Its expression is observed in a variety of tissues. It is overexpressed in a majority of breast cancer cell lines and primary breast tumor lesions. Its EVH2 domain mediates tetramerization, F-actin binding, and actin bundle formation. The EVH2 domain is comprised of three regions: Block A (aa 391-411) is a thymosin-like domain that is essential for G-actin binding; block B (aa 442-459) is required for F-actin binding and subcellular location, and block C (aa 554-588) is required for tetramerization. It also contains a KLKR motif (aa 400-403) within block A that is reported to be essential for G-actin binding and actin polymerization. hMENA is absent in normal breast tissue, but it is overexpressed in breast tumors, where its expression correlates with HER-2-positive, ER-negative, and high Ki 67 phenotype. Depletion of hMENA/ hMENA11 is reported to decrease HER3 phosphorylation, inhibits EGF- and NRG-mediated activation of EGFR and HER-2 and counteract growth factor-mediated cell proliferation. Silencing of hMENA/hMENA11a is reported to switch on molecules linked to apoptosis, including cleaved forms of poly (ADP-ribose) polymerase and caspase 9. A hMENA v6 variant of hMENA has also been described that increases cell invasion. In an isogenic model of human breast cancer progression, hMENA11a expression is observed in premalignant cells, whereas hMENA v6 expression is restricted to invasive cancer cells.
