’Receptor tyrosine kinase which binds promiscuouslyGPI-anchored ephrin-A family ligands residing on adjacent cells,leading to contact-dependent bidirectional signaling intoneighboring cells. The signaling pathway downstream of the receptoris referred to as forward signaling while the signaling pathwaydownstream of the ephrin ligand is referred to as reversesignaling. Among GPI-anchored ephrin-A ligands, EFNA5 is acognate/functional ligand for EPHA7 and their interaction regulatesbrain development modulating cell-cell adhesion and repulsion. Hasa repellent activity on axons and is for instance involved in theguidance of corticothalamic axons and in the proper topographicmapping of retinal axons to the colliculus. May also regulate braindevelopment through a caspase(CASP3)-dependent proapoptoticactivity. Forward signaling may result in activation of componentsof the ERK signaling pathway including MAP2K1, MAP2K2, MAPK1 ANDMAPK3 which are phosphorylated upon activation of EPHA7. Isoform 4which lacks the kinase domain may regulate isoform 1 adhesiveproperties.
