Function
Controls several aspects of neuronal morphogenesis; essential for optic lobe development, EcR-B1 expression in larval brains, mushroom body remodeling, dorsal neuron morphogenesis and motoneuron axon guidance. Ligands Actbeta and daw act redundantly through the Activin receptor Babo and its transcriptional mediator Smad2 (Smox), to regulate neuroblast numbers and proliferation rates in the developing larval brain.
