What is the official name of the BMPR1A gene?
The official name of this gene is “bone morphogenetic protein receptor, type IA.”
BMPR1A is the gene's official symbol. The BMPR1A gene is also known by other names, listed below.

What is the normal function of the BMPR1A gene?
The BMPR1A gene provides instructions for making a protein called bone morphogenetic protein receptor 1A. This receptor protein has a specific site into which certain other proteins, called ligands, fit like keys into locks. Specifically, the BMPR1A protein attaches (binds) to ligands in the transforming growth factor beta (TGF-β) pathway. This signaling pathway allows the environment outside the cell to affect how the cell produces other proteins. The BMPR1A receptor protein and its ligands are involved in transmitting chemical signals from the cell membrane to the nucleus.
When the BMPR1A protein is bound to a ligand, it turns on (activates) a group of related proteins (a protein complex) called SMAD proteins. The activated SMAD protein complex is then transported into the cell's nucleus, where it regulates cell growth and division (proliferation) and the activity of particular genes.
Does the BMPR1A gene share characteristics with other genes?
The BMPR1A gene belongs to a family of genes called CD (CD molecules).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
