Predicted to enable several functions, including ATP binding activity; activin binding activity; and transmembrane receptor protein serine/threonine kinase activity. Involved in response to hypoxia. Located in cell surface; dendrite; and neuronal cell body. Biomarker of pulmonary hypertension and transient cerebral ischemia. Human ortholog(s) of this gene implicated in hereditary hemorrhagic telangiectasia and pulmonary hypertension. Orthologous to human ACVRL1 (activin A receptor like type 1).
