Temrinal γ phosphate protein kinases

WebProtein tyrosine phosphorylation (PTP) is an important posttranslational modification that controls the cell signaling involved in the regulation of a variety of biological processes, including cell growth, proliferation, differentiation, migration, survival, and death. WebThe enzymes that carry out this modification are the protein tyrosine kinases (PTKs), which catalyze the transfer of the γ phosphate of ATP to tyrosine residues on protein substrates. Phosphorylation of tyrosine residues modulates enzymatic activity and creates binding sites for the recruitment of downstream signaling proteins.
