>cd05095 PTKc_DDR2 Catalytic Domain of the Protein Tyrosine Kinase, Discoidin Domain Receptor 2. Protein Tyrosine Kinase (PTK) family; mammalian Discoidin domain receptor 2 (DDR2) and homologs; 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. DDR2 is a member of the DDR subfamily, which are receptor tyr kinases (RTKs) containing an extracellular discoidin homology domain, a transmembrane segment, an extended juxtamembrane region, and an intracellular catalytic domain. The binding of the ligand, collagen, to DDRs results in a slow but sustained receptor activation. DDR2 binds mostly to fibrillar collagens. More recently, it has been reported to also bind collagen X. DDR2 is widely expressed in many tissues wit
