EphrinB (Tyr298) Antibody

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 cellto 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 (Tyr-298) plays a key role in EphrinB signaling (Kalo, et al., 2001) .

Synthetic phosphopeptide corresponding to amino acid residues surrounding the Tyr298 of Xenopus EphrinB, conjugated to keyhole limpet hemocyanin (KLH) .

Specific for endogenous levels of the ~46 kDa EphrinB protein phosphorylated at Tyr298. Immunolabeling is completely eliminated by treatment with λ-phosphatase. Note: Xenopus Tyr298 is the homolog of human, mouse and rat Tyr317 and also chicken Tyr305.
