Protein

Activin receptor type-2A

Gene

Acvr2a

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -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. Mediates induction of adipogenesis by GDF6.By similarity

Catalytic activityi

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

Cofactori

Mg2+By similarity, Mn2+By similarity
