Predicted to enable BMP binding activity; identical protein binding activity; and morphogen activity. Predicted to be involved in several processes, including determination of dorsal identity; negative regulation of BMP signaling pathway; and negative regulation of monocyte chemotaxis. Predicted to act upstream of or within neuron projection morphogenesis and positive regulation of neuron differentiation. Predicted to be active in extracellular space. Orthologous to several human genes including MICOS10-NBL1 (MICOS10-NBL1 readthrough). [provided by Alliance of Genome Resources, Apr 2022]
