PROSITE documentation PDOC50186 [for PROSITE entry PS50186] |
The DEP domain is a globular domain of about 80 residues that is found in more than 50 proteins involved in G protein signaling pathways. It has been named after the three proteins (Dishevelled, Egl-10, and Pleckstrin) in which it was initially identified [1]. 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 [2,3].
Nuclear magnetic resonance spectroscopy has revealed that the DEP domain comprises a three-helix bundle, a β-hairpin 'arm' composed of two β-strands and two short β-strands in the C-terminal region [3].
Representative example of proteins containing DEP domains are listed below:
The profile we developed covers the entire DEP domain.
