BMP4 (Bone Morphogenetic Protein 4) encodes a member of the TGF-beta superfamily of signaling molecules. BMP4 is a multifunctional growth factor critical for embryonic development, tissue patterning, and cell fate determination. In the nervous system, BMP4 regulates neural stem cell proliferation, differentiation, astrogenesis, synaptic formation, and plasticity[1].
Dysregulated BMP4 signaling has been implicated in Alzheimer's Disease, Parkinson's Disease, and autism spectrum disorder, making it an important protein for understanding developmental and degenerative processes in the brain.
BMP4 is synthesized as a precursor protein that undergoes:
