In molecular biology, the DEP domain (Dishevelled, Egl-10 and Pleckstrin domain) is a globular protein domain of about 80 amino acids that is found in over 50 proteins involved in G-protein signalling pathways. It was named after the three proteins it was initially found in:
Mammalian regulators of G-protein signalling also contain these domains, and regulate signal transduction by increasing the GTPase activity of G-protein alpha subunits, thereby driving them into their inactive GDP-bound form. It has been proposed that the DEP domain could play a selective role in targeting DEP domain-containing proteins to specific subcellular membranous sites, perhaps even to specific G protein-coupled signaling pathways.Nuclear magnetic resonance spectroscopy has revealed that the DEP domain comprises a three-helix bundle, a beta-hairpin 'arm' composed of two beta-strands and two short beta-strands in the C-terminal region.
