Abstract:
Bone morphogenetic proteins (BMPs) are secreted extracellular matrix (ECM)-associated proteins that regulate a wide range of developmental processes, including limb and kidney formation. A critical element of BMP regulation is the presence of secreted antagonists that bind and inhibit BMP binding to their cognate Ser/Thr kinase receptors at the plasma membrane. Antagonists such as Noggin, Chordin, Gremlin (Grem1), and twisted gastrulation-1 (Twsg1) have been shown to inhibit BMP action in a range of different cell types and developmental stage-specific contexts. Here we review new developments in the field of BMP and BMP antagonist biology during mammalian development and suggest strategies for targeting these proteins in human disease.

Interactions Between Signaling Pathways
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
