Rhodopsin_N

Rhodopsin_N
PFAM accession number:PF10413
Interpro abstract (IPR019477):

Rhodopsin is the archetypal G-protein-coupled receptor. Such receptors participate in virtually all physiological processes as signalling molecules. They utilise heterotrimeric guanosine triphosphate (GTP)-binding proteins to transduce extracellular signals to intracellular events. Rhodopsin is important because of the pivotal role it plays in visual signal transduction. It is a dimeric transmembrane protein whose intradiskal surface consists of an N-terminal domain and three loops connecting six of the seven transmembrane helices. The N-terminal domain is a compact alpha-helical region with breaks and bends at proline residues outside the membrane [(PUBMED:10888202)]. This entry represents the N-terminal domain, while the transmembrane region is represented by (IPR000276). The N-terminal domain is extracellular is and is necessary for successful dimerisation and molecular stability [(PUBMED:16567090)].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Rhodopsin_N
