EPHA6 (Q9UF33) - Overview - Molecular Target Synopsis


EPHA6, Ephrin type-A receptor 6
Enzyme Classification
UniProt Q9UF33

Also Known as EPHA6_HUMAN, EPHA6, EHK2, HEK12

Receptor tyrosine kinase which binds promiscuously GPI-anchored ephrin-A family ligands 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. Heterotetramer upon binding of the ligand. The heterotetramer is composed of an ephrin dimer and a receptor dimer. Oligomerization is probably required to induce biological responses (By similarity). Interacts (via SAM domain) with ANKS1A (via SAM domain).
