Summary: Enables activin binding activity and protein serine/threonine kinase activity. Involved in peptidyl-threonine phosphorylation. Acts upstream of or within several processes, including activin receptor signaling pathway; hair follicle development; and regulation of gene expression. Predicted to be located in cell surface and cytosol. Predicted to be part of activin receptor complex. Predicted to be active in plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; egg cylinder; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in lung non-small cell carcinoma; lung small cell carcinoma; malignant mesothelioma; pancreatic cancer; and stomach cancer. Orthologous to human ACVR1B (activin A receptor type 1B). [provided by Alliance of Genome Resources, Apr 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.
