HOST SPECIES:Rabbit
SPECIES REACTIVITY: Bovine, Chicken, Human, Mouse, Rat, Xenopus, Zebrafish
IMMUNOGEN: Phosphopeptide corresponding to amino acid residues surrounding the phospho Tyr317 of Chicken EphrinB. Note: Chicken Tyr317 is the homolog of rat and mouse Tyr328, human Tyr329 and Xenopus Tyr310.
TESTED APPLICATIONS: WB
APPLICATIONS: The antibody has been directly tested for reactivity in Western blots with rat tissue. It is anticipated that the antibody will react with bovine, chicken, human, mouse, Xenopus and zebra fish based on the fact that these species have 100% homology with the amino acid sequence used as antigen.

psi-iconBackground and References
BACKGROUND:EphrinB proteins are thought to play key roles in cellular functions as diverse as neuronal migration and blood vessel development (Flanagan and Vanderhaeghen, 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).
