Predicted to enable several functions, including ATP binding activity; enzyme activator activity; and transmembrane receptor protein serine/threonine kinase activity. Predicted to be involved in several processes, including circulatory system development; positive regulation of cell population proliferation; and positive regulation of transmembrane receptor protein serine/threonine kinase signaling pathway. Predicted to act upstream of or within several processes, including animal organ development; limb morphogenesis; and regionalization. Located in dendrite and neuronal cell body. Human ortholog(s) of this gene implicated in hereditary mixed polyposis syndrome 2; intestinal disease; and juvenile polyposis syndrome. Orthologous to human BMPR1A (bone morphogenetic protein receptor type 1A). [provided by Alliance of Genome Resources, Apr 2022]
