: It initiates bone and cartilage development and is particularly critical for patterning teeth. Mutations in BMP4 are linked to tooth agenesis (missing teeth).

: It primarily signals through two routes: : It initiates bone and cartilage development and

: Binding to Type I (ALK3/ALK6) and Type II (BMPR2) receptors triggers the phosphorylation of R-Smads (Smad1/5/8) , which complex with Smad4 and move into the nucleus to regulate gene expression. Biological Structure & Mechanisms BMP4 is synthesized as

: It typically suppresses "default" neural differentiation to promote skin formation; however, in the adult brain, it helps maintain neural stem cell pools. Metabolic & Clinical Significance in the adult brain

is a versatile secreted signaling molecule belonging to the TGF-beta superfamily . Known for its critical role in early development and tissue homeostasis, it acts as a "master controller" for cellular fate. Biological Structure & Mechanisms

BMP4 is synthesized as a 408-residue preproprotein that undergoes specific proteolytic cleavage to become a mature 116-residue active peptide.
