Protein

Activin receptor type-2A

Gene
Acvr2a, Actrii, Acvr2
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

On ligand binding, forms a receptor complex consisting of two type II and two type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators. Receptor for activin A, activin B and inhibin A.

Catalytic activityi

ATP + [receptor-protein] = ADP + [receptor-protein] phosphate.

Cofactori

Magnesium or manganese By similarity.
