| protein-tyrosine kinase | <enzyme> An enzyme that catalyses the phosphorylation of tyrosine residues in proteins with ATP or other nucleotides as phosphate donors.12. Chemical name: ATP:protein-tyrosine O-phosphotransferase Registry number: EC 2.7.1.112 (12 Dec 1998) |
|---|---|
| protein-tyrosine-phosphatase | <enzyme> An enzyme group that specifically dephosphorylates phosphotyrosyl residues in selected proteins. Together with protein-tyrosine kinase, it regulates tyrosine phosphorylation and dephosphorylation in cellular signal transduction and may play a role in cell growth control and carcinogenesis. Chemical name: Protein-tyrosine-phosphate phosphohydrolase Registry number: EC 3.1.3.48 (12 Dec 1998) |

| nonreceptor protein tyrosine kinase | <enzyme> Kinases that phosphorylate protein tyrosine residues. These kinases play major roles in mitogenic signalling and can be divided into two subfamilies: receptor tyrosine kinases, that have an extracellular ligand binding domain, a single transmembrane domain and an intracellular tyrosine kinase domain and nonreceptor tyrosine kinases, which are soluble, cytoplasmic kinases. (18 Nov 1997) |
