Structural highlights

Disease

[BMP1_HUMAN] Defects in BMP1 are the cause of osteogenesis imperfecta 13 (OI13) [MIM:614856]. An autosomal recessive form of osteogenesis imperfecta, a connective tissue disorder characterized by bone fragility, low bone mass, and recurrent fractures. OI13 is characterized by normal teeth, faint blue sclerae, severe growth deficiency, borderline osteoporosis, severe bone deformity, and recurrent fractures affecting both upper and lower limbs.^{[1] [2]}

Function

[BMP1_HUMAN] Cleaves the C-terminal propeptides of procollagen I, II and III. Induces cartilage and bone formation. May participate in dorsoventral patterning during early development by cleaving chordin (CHRD). Responsible for the proteolytic activation of lysyl oxidase LOX.
