Western blot of rat testes lysate showing specific immunolabeling of the ~46 kDa EphrinB phosphorylated at Tyr298 (Lane 1). The phosphospecificty of this labeling is shown in Lane 2 (lambda-phosphatase). The blot is identical to the control except that it was incubated in lambda-phosphatase (1200 units for 30 min) before being exposed to the Anti-Tyr298 EphrinB. The immunolabeling of the EphrinB band is completely eliminated by treatment with lambda-phosphatase.

This antibody is predicted to react with bovine, canine, human, mouse, non-human primate, Xenopus and zebrafish based on 100% sequence homology.
This antibody is specific for the ~46 kDa EphrinB protein phosphorylated at Tyr298. Immunolabeling can be blocked by lambda-phosphatase treatment.
EphrinB proteins are thought to play key roles in cellular functions as diverse as neuronal migration and blood vessel development (Flanagan and Vancerhaeghen, 1998; Dufour et al, 2003; Oike et al, 2002). EphrinB molecules expressed at the membrane surface bind to the EphB family receptors on target cells during cell-to cell contact. This interaction leads to cell signaling in the target cell but also generates a reverse signal in the cell expressing EphrinB on its surface. This reverse signaling event is thought to be critical for vessel maturation and neuronal development. Importantly, tyrosine phosphorylation of EphrinB is thought to be a critical component of this reverse signaling event (Palmer et al, 2002). Recent work suggests that phosphorylation of a specific EphrinB residue (Tyr298) plays a key role in EphrinB signaling (Kalo, et al, 2001).
