Sujet: Syk is a non-receptor protein-tyrosine kinase that is closely related to ZAP70 and plays crucial roles in the development and receptor-mediated signaling of most leukocytes and in vascular integrity. Syk is expressed in hematopoietic cells, including B lymphocytes, immature (CD4, CD8 double-negative and double-positive) thymocytes, and myeloid cells, epithelial cell lines, and normal breast tissue. Mature (CD4 or CD8 single-positive) thymocytes and peripheral alphabeta TCR-bearing T lymphocytes have very low or undetectable levels of Syk. Syk contributes to the signal transduction process by binding to ITAMs (Immunoreceptor Tyrosine-based Activation Motifs) of immune receptors, including Igalpha and Igbeta (CD79a and b), TCRzeta, CD3epsilon, and FcRgamma. Upon receptor activation, Syk binds to phosphorylated ITAMs via its two N-terminal SH2 domains thereby activating Syk and causing tyrosines in the interdomain, between the SH2 and Kinase domains of Syk, to undergo auto-phosphorylation and phosphorylation by Lyn. The tyrosine 348 phosphorylation site (pY348) in human Syk is orthologous to tyrosine 342 in mouse and rat Syk and tyrosine 315 in human ZAP70. This phosphorylated site can act as a binding site for other signaling molecules, such as PLCgamma, Vav, and Fgr. The I120-772 antibody is specific for human Syk (pY348) and does not cross-react with phosphorylated Zap70. The orthologous phosphorylation site in mouse and rat Syk is Y342.
