| 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) |
|---|---|
| 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.

| epidermal growth factor receptor protein-tyrosine kinase | <enzyme> The catalytic protein-tyrosine kinase domain found on the cytoplasmic beta-portion of epidermal growth factor receptor. Registry number: EC 2.7.1.- (12 Dec 1998) |
| lymphocyte specific protein tyrosine kinase p56(lck) | <enzyme> This enzyme is a lymphoid specific src family tyrosine kinase that is critical for T-cell development and activation. Lck is associated with the cytoplasmic domains of CD4, CD8 and the beta-chain of the il-2 receptor, and is thought to be involved in the earliest steps of tcr-mediated T-cell activation.
