Enzyme Information

2.7.11.30
Receptor protein serine/threonine kinase.
based on mapping to UniProt P38445
ATP + [receptor-protein] = ADP + [receptor-protein] phosphate.
-!- The transforming growth factor beta (TGF-beta) family of cytokines regulates cell proliferation, differentiation, recognition and death. -!- Signaling occurs by the binding of ligand to the type II receptor, which is the constitutively active kinase. -!- Bound TGF-beta is then recognized by receptor I, which is phosphorylated and can propagate the signal to downstream substrates. -!- Formerly EC 2.7.1.37.
