Proline-rich tyrosine kinase 2 (Pyk2) is a cytoplasmic, non-receptor tyrosine kinase implicated in multiple signaling pathways.Direct receptor-receptor interactions involving Ig-like domain 4 stabilize the receptor dimerization, which is primarily caused by ligand binding to Ig-like domains 2 and 3.The juxtaposition of the intracellular components during dimerization, which encourages autophosphorylation in trans between the receptors, is a crucial step in activation. The phosphorylated PDGFR then recruits molecules with SH2 domains like Src kinase, Grb2, SHP2, PLC, Nck, and STAT to start various downstream signaling events.
More than 60% of hepatocellular carcinoma (HCC) patients' tumors have elevated levels of Pyk2, a FAK family non-receptor tyrosine kinase.
