Figure: BMP7 signaling leading to osteoblast differentiation (Human)¶
The drawing depicts the BMP7 signaling pathway leading to osteoblast differentiation in humans. In this pathway:
-
BMP7 (bone morphogenetic protein 7), shown as a pink circle in the extracellular space, acts as a growth factor.
-
BMP7 binds to and activates type II (ACVR2A) and type I (ACVR1) receptors on the plasma membrane, represented as blue rectangles.
-
Activated receptors phosphorylate and activate R-SMAD proteins (SMAD1, SMAD5, and SMAD9), shown as green circles in the cytoplasm.
-
Activated SMADs translocate to the nucleus where they bind to chromatin (brown wavy line).
-
SMAD proteins function as transcription factors, initiating the expression of genes that drive osteoblast differentiation.
The entire process is part of the BMP signaling pathway (GO:0030509), which ultimately leads to osteoblast differentiation (GO:0001649).
