UniProt Number
UniProt SummaryFUNCTION: SwissProt: P43405 # Positive effector of BCR-stimulated responses. Couples the B-cell antigen receptor (BCR) to the mobilization of calcium ion either through a phosphoinositide 3-kinase-dependent pathway, when not phosphorylated on tyrosines of the linker region, or through a phospholipase C-gamma-dependent pathway, when phosphorylated on Tyr-348 and Tyr-352. Thus the differential phosphorylation of Syk can determine the pathway by which BCR is coupled to the regulation of intracellular calcium ion (By similarity).
SIZE: 635 amino acids; 72066 Da
SUBUNIT: Interacts with CBL and SLA when it is phosphorylated. The interaction with SLA may link it to CBL, leading to its destruction. Interacts with phosphorylated NFAM1 (By similarity). Interacts with Epstein-Barr virus LMP2A. Interacts through its SH2 domains with the phosphorylated ITAM domain of CD79A which stimulates SYK autophosphorylation and activation.
PTM: Autophosphorylated. & Phosphorylation on Tyr-323 creates a binding site for c-Cbl, an adapter protein that serves as a negative regulator of BCR- stimulated calcium ion signaling (By similarity). & Phosphorylation on Tyr-348 and Tyr-352 enhances the phosphorylation and activation of phospholipase C-gamma and the early phase of calcium ion mobilization via a phosphoinositide 3- kinase-independent pathway (By similarity). & Ubiquitinated by CBLB after BCR activation; which promotes proteasomal degradation (By similarity).
SIMILARITY: SwissProt: P43405 ## Belongs to the protein kinase superfamily. Tyr protein kinase family. SYK/ZAP-70 subfamily. & Contains 1 protein kinase domain. & Contains 2 SH2 domains.

FAQ

QuestionAnswer
What is the Molar extinction coefficient for Adenosine 5'-[g32P]triphosphate ([g32P]ATP) used in the kinase assay?The Molar extinction coefficient is 15400.
What is the best way to store and thaw enzymes?In order to maintain activity of enzymes, we recommend a slow thaw and aliquot storage. To do this, remove the full vial from the freezer and place under cold running tap water. Once thawed, place the vial on ice, gently mix, than make aliquots. Using liquid nitrogen or an ethanol/dry ice bath, flash freeze the aliquots. Store aliquots at the recommended temperature.
