Protein family
Eph receptors (Ephs , after erythropoietin-producing human hepatocellular receptors ) are a group of receptors that are activated in response to binding with Eph receptor-interacting proteins (Ephrins) . Ephs form the largest known subfamily of receptor tyrosine kinases (RTKs). Both Eph receptors and their corresponding ephrin ligands are membrane-bound proteins that require direct cell-cell interactions for Eph receptor activation. Eph/ephrin signaling has been implicated in the regulation of a host of processes critical to embryonic development including axon guidance ,[ 1] formation of tissue boundaries,[ 2] cell migration , and segmentation .[ 3] Additionally, Eph/ephrin signaling has been identified to play a critical role in the maintenance of several processes during adulthood including long-term potentiation ,[ 4] angiogenesis ,[ 5] and stem cell differentiation and cancer .[ 6]
