Mouse Anti-Human SYK

This product recognizes protein tyrosine kinase p72^syk (syk), a 72kDa non-receptor tyrosine kinase, critical for immunoreceptor signaling in hematopoietic cells, but also expressed by nonhematopoietic cells, including fibroblasts, endothelial cells and hepatocytes.

Syk plays an important role in mast cell response, initiated by the aggregation of the IgE high affinity receptor Fc epsilon R1. Phosphorylation of ITAMs within Fc receptor R1 by another tyrosine kinase lyn, results in the recruitment of syk, which is then responsible for the further phosphorylation of numerous target proteins within many different signal transduction pathways.

Further studies have shown that syk also plays a major role in B cell receptor-mediated apoptosis, proliferation and hematopoiesis. Syk is also reported to associate with protein kinase C alpha during platelet activation.
