Molecular cloning and characterization of a novel rat activin receptor

Biochem Biophys Res Commun. 1992 Mar 16;183(2):672-9. doi: 10.1016/0006-291x(92)90535-s.


We report the isolation of a full-length rat cDNA for a new activin receptor. The deduced amino acid sequence of this receptor shows 67 percent overall identity with that of a previously identified mouse activin receptor. As predicted for the mouse activin receptor, the amino acid sequence of the rat receptor is consistent with a polypeptide containing an extracellular ligand binding domain, a hydrophobic transmembrane domain, and a serine/threonine kinase intracellular domain. In an expression assay, this new receptor was found to bind I125 radiolabeled activin.
