Comments

FUNCTION: 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.
CATALYTIC ACTIVITY: ATP + [receptor-protein] = ADP + [receptor-protein] phosphate.
COFACTOR: Magnesium or manganese (By similarity).
SUBUNIT: Interacts with AIP1. Part of a complex consisting of AIP1, ACVR2A, ACVR1B and SMAD3 (By similarity).
SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
TISSUE SPECIFICITY: Urogenital ridge, testis, ovary, brain and lungs.
SIMILARITY: Belongs to the protein kinase superfamily. TKL Ser/Thr protein kinase family. TGFB receptor subfamily.
SIMILARITY: Contains 1 GS domain.
SIMILARITY: Contains 1 protein kinase domain.
