>cd05046 PTK_CCK4 Catalytic Domain of the Protein Tyrosine Kinase, Colon Carcinoma Kinase 4. Protein Tyrosine Kinase (PTK) family; Colon carcinoma kinase 4 (CCK4); pseudokinase domain. The PTKc (catalytic domain) family, to which this subfamily belongs, 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. CCK4, also called protein tyrosine kinase 7 (PTK7), is an orphan receptor tyr kinase (RTK) containing an extracellular region with seven immunoglobulin domains, a transmembrane segment, and an intracellular inactive pseudokinase domain. Studies in mice reveal that CCK4 is essential for neural development. Mouse embryos containing a truncated CCK4 die perinatally and display craniorachischisis, a severe form of neural tube defect. The mechanism of action of the CCK4 pseudokinase is stil
