Subunit structurei
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.
Forms a ternary EFNA5-EPHA3-ADAM10 complex mediating EFNA5 extracellular domain shedding by ADAM10 which regulates the EFNA5-EPHA3 complex internalization and function.
Interacts (phosphorylated) with PTPN1; dephosphorylates EPHA3 and may regulate its trafficking and function.
Interacts (phosphorylated) with CRK; mediates EFNA5-EPHA3 signaling through RHOA GTPase activation.
Interacts with NCK1 (via SH2 domain); mediates EFNA5-EPHA3 signaling (By similarity).
