This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of SMAD family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate each subunit of the disulfide-linked homodimer. The encoded protein stimulates thermogenesis in brown adipose tissue. Expression of this gene may be downregulated in pancreatic cancer. This gene may have arose from a gene duplication event and its gene duplicate is also present on chromosome 1.BMP8B (Bone Morphogenetic Protein 8b) is a Protein Coding gene. Diseases associated with BMP8B include Achondroplasia and Blue Color Blindness. Among its related pathways are PEDF Induced Signaling and TGF-Beta Pathway. GO annotations related to this gene include cytokine activity and transforming growth factor beta receptor binding. An important paralog of this gene is BMP8A.
