The Bone Morphogenetic Protein (BMP) signaling pathway is one of two branches of Transforming Growth Factor-β family signaling in Drosophila. The binding of a BMP family dimer to a heterodimeric serine/threonine kinase receptor complex (composed of type I and type II subunits), results in the phosphorylation and activation of the type I receptor by the type II subunit. In the BMP branch, the downstream target of the type I receptor is Mad, a member of the Smad family. Mad forms a complex with the co-Smad, Med. This complex translocates into the nucleus and regulates the transcription of target genes in concert with other nuclear cofactors. (Adapted from FBrf0236482.)

Note: Pathway Pages in FlyBase are under development. The pathway gene tables display genes that have been experimentally shown to act within the pathway or modify pathway activity. We welcome any feedback to help improve the usefulness and accuracy of these gene lists.
