General description
EPHB1 (Ephb1 Eph receptor B1) is a glutamatergic synapse forming tyrosine kinase. Mammals contain five EPHB receptors, namely, EPHB1-EPHB4 and EPHB6. Their ligands are transmembrane in nature and are called ephrinB1, -B2 and -B3.
Application
EPHB1 (591-end), active, GST tagged from mouse has been used for in vitro phosphorylation of Caskin1.
Biochem/physiol Actions
EPHB1 (Ephb1 Eph receptor B1) is a member of the Eph family of receptor tyrosine kinases. Ligand-activated EPHB1 forms a signaling complex with Nck, paxillin, and focal adhesion kinase and induces tyrosine phosphorylation of paxillin in a c-Src-dependent manner to promote cell migration. In addition, activated EPHB1 recruits the adaptor proteins Grb2 and p52Shc and promotes p52Shc and c-Src tyrosine phosphorylation as well as MAPK/extracellular signal-regulated kinase (ERK) activation. Expression of dominant-negative c-Src significantly reduced EPHB1-dependent ERK1/2 activation and chemotaxis. This receptor is essential for the maintenance of hyperalgesia, and is the predominant receptor for chronic pain in the spinal cord.
