[1]	NUCLEOTIDE SEQUENCE [MRNA]. Ethier J.-F., Lussier J.G., Daneau I., Silversides D.W.; "Bovine activin receptor type I can be expressed as a kinase-domain truncated receptor."; Submitted (JUN-1996) to the EMBL/GenBank/DDBJ databases.

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. Receptor for TGF-beta. May also bind activin.
CATALYTIC ACTIVITY: ATP + [receptor-protein] = ADP + [receptor-protein] phosphate.
COFACTOR: Magnesium or manganese (By similarity).
SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
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.
