Summary: Enables morphogen activity and protein heterodimerization activity. Involved in several processes, including synapse organization; trans-synaptic signaling; and wing disc development. Located in dense core granule. Is active in extracellular space. Is expressed in several structures, including germ layer; gonadal somatic stem cell; gut section; imaginal disc; and somatic cell of ovariole. Used to study diabetes mellitus and obesity. Human ortholog(s) of this gene implicated in prostate cancer. Orthologous to several human genes including BMP5 (bone morphogenetic protein 5); BMP7 (bone morphogenetic protein 7); and BMP8A (bone morphogenetic protein 8a).
