BMP4 is synthesized as a 408-residue preproprotein that undergoes specific proteolytic cleavage to become a mature 116-residue active peptide.
: It primarily signals through two routes: BMP4 is synthesized as a 408-residue preproprotein that
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
: It can also directly activate pathways like ERK, p38 MAPK, and JNK to regulate migration and survival. BMP4 is synthesized as a 408-residue preproprotein that
: 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.
