NCI: EPH tyrosine kinase 1 is a member of the largest subfamily of RTKs. EPH-related receptors have been implicated in mediating developmental events, particularly in the nervous system. EPH-family receptors typically have a single kinase domain and an extracellular region containing a Cys-rich domain and two fibronectin type III repeats. EPH receptors are divided into two groups based on their extracellular domain sequences and affinities for ephrin-A (EPHA) and ephrin-B ligands (EPHB). Ephrin-A2 forms a stable complex with the metalloproteinase Kuzbanian, involving interactions outside the cleavage region and the protease domain. EPH tyrosine kinase 1 receptor binding triggers ephrin-A2 cleavage in a localized reaction specific to the cognate ligand. (from OMIM 179610 and NCI)
