NCIt definition : Ephrin type-A receptor 4 (986 aa, 110 kDa) is encoded by the human EPHA4 gene. This
protein plays a role in neuronal morphology, cell-cell signaling, tyrosine phosphorylation
and the regulation of GTPase activity.;
NCIt note : The signaling pathways downstream of ephrin receptors are referred to as forward signaling
while the signaling pathways downstream of the ephrin ligands are referred to as reverse
signaling. (UniProt);
