Enables peptidase activity. Acts upstream of or within several processes, including collagen biosynthetic process; determination of ventral identity; and fin development. Predicted to be active in extracellular space. Is expressed in several structures, including alar plate midbrain region; central nervous system; mesenchyme median fin fold; mesoderm; and optic vesicle. Used to study osteogenesis imperfecta and osteogenesis imperfecta type 13. Human ortholog(s) of this gene implicated in osteogenesis imperfecta type 13. Orthologous to human BMP1 (bone morphogenetic protein 1).
