|Homo sapiens spleen tyrosine kinase (SYK), transcript variant 1|
|Syk, a non-receptor tyrosine kinase, belongs to the Syk-Zap70 family of protein tyrosine kinase (PTK) and is involved in a wide variety of cellular functions including the pathogenesis of malignant cancer (1). Ubiquitously expressed in hematopoietic cells, Syk has been found to be an effector of B cell receptor (BCR) and functions in B & T cell lymphopoiesis. In the absence of Syk, B cell development is blocked (2). Upon binding to the BCR and to the cell surface receptor of hematopoietic cells (3), Syk is activated and phosphorylates Phospholipase C resulting in the downstream activation of ERK & JNK kinase. Syk also phosphorylates PI3-K activating the Akt pathway (4). Cross-linking of the T cell antigen receptor (TCR)-CD3 complex induces rapid tyrosine phosphorylation and then activation of Syk, which in turn phosphorylates a multitude of intracellular substrates such as Cbl (5). Substitution of Tyr-525 and Tyr-526 at the autophosphorylation site of Syk in mCD8-Syk substantially reduced the kinase activity and the binding to PLC-gamma1 SH2(C) in vitro (6). |
