>cd05116 PTKc_Syk Catalytic Domain of the Protein Tyrosine Kinase, Spleen tyrosine kinase. Protein Tyrosine Kinase (PTK) family; Spleen tyrosine kinase (Syk); catalytic (c) domain. The PTKc family is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, and phosphoinositide 3-kinase (PI3K). PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Syk, together with Zap-70, form the Syk subfamily of kinases which are cytoplasmic (or nonreceptor) tyr kinases containing two Src homology 2 (SH2) domains N-terminal to the catalytic tyr kinase domain. Syk was first cloned from the spleen, and its function in hematopoietic cells is well-established. Syk is involved in the signaling downstream of activated receptors (including B-cell and Fc receptors) that contain ITAMs (immunoreceptor tyr activation motifs), leading to processes such as cell proliferatio
