BMPR1A is a human gene whose product bMPR1B (Bone Morphogenetic Protein Receptor Type 1B) is a serine/threonine receptor kinase that transduces signals from bone morphogenetic proteins (BMPs), which are members of the TGF-β superfamily. BMPR1B forms complexes with BMPR2 to initiate downstream signaling through SMAD1/5/8 phosphorylation. Variants in BMPR1A have been implicated in Neurodegenerative Diseases, Other Conditions. This page covers the gene's normal function, disease associations, expression patterns, and key research findings relevant to neurodegeneration.

In the nervous system, BMPR1B plays important roles in:
BMPR1B is expressed in various brain regions and has been implicated in neurodegenerative diseases, particularly Parkinson's disease where BMP signaling may protect dopaminergic neurons.
