: Factors like Noggin, Chordin, and Gremlin act as "ligand traps," preventing BMP4 from binding to its receptors. This balance is vital for correct organ patterning. Key Functions in Development
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 : Factors like Noggin, Chordin, and Gremlin act
Beyond development, BMP4 is a major player in adult metabolism and disease. : Factors like Noggin
: It can also directly activate pathways like ERK, p38 MAPK, and JNK to regulate migration and survival. and Gremlin act as "ligand traps
: It initiates bone and cartilage development and is particularly critical for patterning teeth. Mutations in BMP4 are linked to tooth agenesis (missing teeth).
