Function
BMPs interact with specific receptors on the cell surface, referred to as bone morphogenetic protein receptors (BMPRs).
Signal transduction through BMPRs results in mobilization of members of the SMAD family of proteins. The signaling pathways involving BMPs, BMPRs and Smads are important in the development of the heart, central nervous system, and cartilage, as well as post-natal bone development.
They have an important role during embryonic development on the embryonic patterning and early skeletal formation. As such, disruption of BMP signaling can affect the body plan of the developing embryo. For example, BMP4 and its inhibitors noggin and chordin help regulate polarity of the embryo (i.e. back to front patterning).
Mutations in BMPs and their inhibitors (such as sclerostin) are associated with a number of human disorders which affect the skeleton.
Several BMPs are also named 'cartilage-derived morphogenetic proteins' (CDMPs), while others are refer to as 'growth differentiation factors' (GDFs).
