Target Data

Function	Cell surface GPI-bound ligand for Eph receptors, a family of receptor tyrosine kinases which are crucial for migration, repulsion and adhesion during neuronal, vascular and epithelial development. Binds promiscuously Eph receptors residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. The signaling pathway downstream of the receptor is referred to as forward signaling while the signaling pathway downstream of the ephrin ligand is referred to as reverse signaling. Induces compartmentalized signaling within a caveolae-like membrane microdomain when bound to the extracellular domain of its cognate receptor. This signaling event requires the activity of the Fyn tyrosine kinase. Activates the EPHA3 receptor to regulate cell-cell adhesion and cytoskeletal organization. With the receptor EPHA2 may regulate lens fiber cells shape and interactions and be important for lens transparency maintenance. May function actively to stimulate axon fasciculation. The interaction of EFNA5 with EPHA5 also mediates communication between pancreatic islet cells to regulate glucose-stimulated insulin secretion. Cognate/functional ligand for EPHA7, their interaction regulates brain development modulating cell-cell adhesion and repulsion.
Gene References into Functions	These results indicate a novel mechanism of ephrin-Eph signaling independent of direct cell contact and proteolytic cleavage and suggest the participation of EphB2(+) extracellular vesicles in neural development and synapse physiology. PMID: 27354374 MiR-96 and miR-182 are upregulated in hepatocellular carcinoma and negatively associated with ephrin A5 expression. PMID: 25663355 the structure of the ligand-binding domain of the EphA3 receptor in complex with its preferred ligand, ephrin-A5, is reported. PMID: 25993310 The genetic variations c.668C>T (rs201008479), c.102C>T (rs199980747) and c.-27C>G (rs200187971) may present an additional genetic risk factor for age-related cataract in the Chinese population. PMID: 25300504 Data indicate that ephrin-A5 binding directly facilitates the formation of Eph/ephrin clusters by inducing conformational changes in the ligand-binding domain (LBD) of EphA4. PMID: 23959867 Transgenic ephrin-A5 plays a critical role in postnatal lens fiber organization to maintain lens transparency: cells in the ephrin-A5-deficient lens are severely disorganized PMID: 23401654 EphrinA5, especially ephrinA5S, acts as a tumor suppressor in hepatocarcinogenesis. PMID: 22860012 This study presented that EFNA5 showed strong associations with alcohol withdrawal symptoms. PMID: 22072270 Data suggest that ephrinA5 mRNA/protein levels are reduced in colon adenocarcinoma compared to normal colon tissue; staging/grading indicates that ephrinA5 inhibits colon adenocarcinoma progression via c-Cbl-mediated EGFR ubiquitination/degradation.

PMID: 18563700 ephrinA5 acted as a tumor suppressor in glioma, and its negative regulation of EGFR contributed to the suppressive effects.
