Abstract

Secreted signaling proteins play fundamental roles in the embryonic patterning of multicellular organisms from insects to humans. Three protein families, bone morphogenetic proteins (BMPs), Wnts, and hedgehog (Hh) are secreted cell—cell signaling molecules that have been shown to be important regulators of a wide variety of normal and pathological developmental processes. BMPs, Wnts, and Hh can all be termed as morphogens in that they act directly at a distance and induce distinct differentiation programs at different concentrations. Signaling by BMPs, Wnts, and Hh is regulated in both positive and negative fashions at the extracellular, membrane, cytoplasmic, and nuclear levels. The range of molecular strategies involved in regulating the signaling activities of these proteins in a developing embryo highlights the crucial importance of maintaining tight spatial and temporal control of morphogens during development.
