>cd05049 PTKc_Trk Catalytic Domain of the Protein Tyrosine Kinases, Tropomyosin Related Kinases. Protein Tyrosine Kinase (PTK) family; Tropomyosin related kinase (Trk) subfamily; catalytic (c) domain. The Trk subfamily consists of TrkA, TrkB, TrkC, and similar proteins. 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. Trk subfamily members are receptor tyr kinases (RTKs) containing an extracellular region with arrays of leucine-rich motifs flanked by two cysteine-rich clusters followed by two immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. Binding to their ligands, the nerve growth factor (NGF) family of neutrotrophins, leads to Trk receptor oligomerization and activation of the catalyt
