Protocol
Specificity / Sensitivity
Phospho-Syk (Tyr323) Antibody detects endogenous levels of Syk only when phosphorylated at Tyr323. It does not cross-react with other tyrosine-phosphorylated members of the Syk/Zap-70 tyrosine kinase family.
Species Reactivity:
Human
The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.
Species predicted to react based on 100% sequence homology:
Mouse, Rat
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr323 of human Syk or Tyr317 of mouse Syk. Antibodies are purified by protein A and peptide affinity chromatography.
Background
Syk is a protein tyrosine kinase that plays an important role in intracellular signal transduction in hematopoietic cells (1-3). Syk interacts with immunoreceptor tyrosine-based activation motifs (ITAMs) located in the cytoplasmic domains of immune receptors (4). It couples the activated immunoreceptors to downstream signaling events that mediate diverse cellular responses, including proliferation, differentiation, and phagocytosis (4). There is also evidence of a role for Syk in nonimmune cells and investigators have indicated that Syk is a potential tumor suppressor in human breast carcinomas (5). Tyr323 is a negative regulatory phosphorylation site within the SH2-kinase linker region in Syk. Phosphorylation at Tyr323 provides a direct binding site for the TKB domain of Cbl (6,7). Tyr352 of Syk is involved in the association of PLCγ1 (8). Tyr525 and Tyr526 are located in the activation loop of the Syk kinase domain; phosphorylation at Tyr525/526 of human Syk (equivalent to Tyr519/520 of mouse Syk) is essential for Syk function (9).
