Summary: Predicted to enable several functions, including ATP binding activity; I-SMAD binding activity; and activin binding activity. Predicted to contribute to activin receptor activity and growth factor binding activity. Involved in several processes, including activin receptor signaling pathway; cardiac fibroblast cell development; and positive regulation of biosynthetic process. Predicted to be located in cell surface. Predicted to be part of activin receptor complex. Predicted to be active in plasma membrane. Human ortholog(s) of this gene implicated in lung non-small cell carcinoma; lung small cell carcinoma; malignant mesothelioma; pancreatic cancer; and stomach cancer.

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.
