Protein Structure

UniProt Annotation

Function

Serine/threonine protein kinase which forms a receptor complex on ligand binding. The receptor complex consisting of 2 type II and 2 type I transmembrane serine/threonine kinases. Type II receptors phosphorylate and activate type I receptors which autophosphorylate, then bind and activate SMAD transcriptional regulators, SMAD2 and SMAD3. Receptor for activin AB, activin B and NODAL. Plays a role in cell differentiation, growth arrest and apoptosis. {ECO:0000269PubMed:12063393, ECO:0000269PubMed:15531507}.

Subcellular Localization

Membrane {ECO:0000269PubMed:12606401}; Single-pass type I membrane protein {ECO:0000269PubMed:12606401}.

Disease Associations

Tissue Specificity

Present in pancreas, heart, colon, small intestine, ovary and the hippocampus, medulla oblongata and putamen of the brain. Isoform 1, isoform 2, isoform 3 and isoform 4 are all expressed in the placenta throughout pregnancy. {ECO:0000269PubMed:12063393, ECO:0000269PubMed:12606401}.
