Structure/function studies of lin-12/Notch proteins

Abstract:
The lin-12/Notch proteins appear to act as transmembrane receptors for intercellular signals that specify cell fates during animal development. Recent structure/function studies have shown that the lin-12/Notch intracellular domain alone has the intrinsic signal-transducing activity of the intact protein, and that the role of the extracellular domain is to regulate this intrinsic activity. These studies have also suggested that the different lin-12/Notch proteins in a given organism are interchangeable biochemically and have addressed the role of lin-12/Notch genes in development.

Ligand Binding Sites
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

Structural Protein Function
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity. In bones and teeth, it mineralizes to form...
Notch Signaling Pathway
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...
