Summary: Enables several functions, including PDZ domain binding activity; activin binding activity; and transmembrane receptor protein serine/threonine kinase activity. Involved in BMP signaling pathway. Acts upstream of or within several processes, including Sertoli cell proliferation; copulation; and regionalization. Located in cell surface. Is active in plasma membrane. Is expressed in several structures, including central nervous system; early conceptus; gonad; gut; and sensory organ. Used to study Weissenbacher-Zweymuller syndrome. Human ortholog(s) of this gene implicated in Lynch syndrome and colon cancer. Orthologous to human ACVR2A (activin A receptor type 2A). [provided by Alliance of Genome Resources, Jul 2025]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
