>cd05036 PTKc_ALK_LTK Catalytic Domain of the Protein Tyrosine Kinases, Anaplastic Lymphoma Kinase and Leukocyte Tyrosine Kinase. Protein Tyrosine Kinase (PTK) family; Anaplastic lymphoma kinase (ALK) and Leukocyte tyrosine (tyr) kinase (LTK); 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 tyr residues in protein substrates. ALK and LTK are orphan receptor tyr kinases (RTKs) whose ligands are not yet well-defined. RTKs contain an extracellular ligand-binding domain, a transmembrane region, and an intracellular tyr kinase domain. They are usually activated through ligand binding, which causes dimerization and autophosphorylation of the intracellular tyr kinase catalytic domain. ALK appears to play an important role in mammalian neural development as well
