Protein tyrosine phosphatase - Wikipedia

WebA tyrosine kinase inhibitor ( TKI) is a pharmaceutical drug that inhibits tyrosine kinases. Tyrosine kinases are enzymes responsible for the activation of many proteins by signal transduction cascades. The proteins are activated by adding a phosphate group to the protein ( phosphorylation ), a step that TKIs inhibit.

Protein Tyrosine Phosphatase - an overview

WebNucleotides, the fundamental units of RNA (ribonucleic acid) and DNA (deoxyribonucleic acid), contain a phosphate molecule attached to a nucleoside, a compound made up of a ribose moiety and a purine or pyrimidine base. In polymers of RNA and DNA, the backbone is composed of repeating phospho-ribose units. WebMar 30, 2024 · The catalytic activity of p56 lck is repressed by phosphorylation of a conserved carboxy-terminal tyrosine residue (tyrosine 505).
