Receptor protein serine/threonine kinase

From Wikipedia, the free encyclopedia

In enzymology, a receptor protein serine/threonine kinase (EC 2.7.11.30) is an enzyme that catalyzes the chemical reaction

ATP + [receptor-protein] $\rightleftharpoons$ ADP + [receptor-protein] phosphate

Thus, the two substrates of this enzyme are ATP and [[[receptor-protein]]], whereas its two products are ADP and [[[receptor-protein] phosphate]].

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups protein-serine/threonine kinases. The systematic name of this enzyme class is ATP:[receptor-protein] phosphotransferase. Other names in common use include activin receptor kinase, receptor type I serine/threonine protein kinase, receptor type II serine/threonine protein kinase, STK13, TGF-beta kinase, and receptor serine/threonine protein kinase. This enzyme participates in 7 metabolic pathways: mapk signaling pathway, cytokine-cytokine receptor interaction, tgf-beta signaling pathway, adherens junction, colorectal cancer, pancreatic cancer, and chronic myeloid leukemia.

[edit] Structural studies
