General Information
NameOR6A2
DescriptionOlfactory receptor 6a2 (olfactory receptor 11-55) (or11-55) (hp2 olfactory receptor).
SpeciesHomo sapiens (NCBI taxonomy ID: 9606)
GO0007165 signal transduction (NAS)
Domain Architecture (Details)
InterPro domains unassigned to SynO:
G-protein-coupled receptors.PCRs.onstitute a vast protein family that encompasses a wide range of functions (including various autocrine.aracrine and endocrine processes). They show considerable diversity at the sequence level.n the basis of which they can be separated into distinct groups. We use the term clan to describe the GPCRs.s they embrace a group of families for which there are indications of evolutionary relationship.ut between which there is no statistically significant similarity in sequence . The currently known clan members include the rhodopsin-like GPCRs.he secretin-like GPCRs.he cAMP receptors.he fungal mating pheromone receptors.nd the metabotropic glutamate receptor family. There is a specialized database for GPCRs: http://www.gpcr.org/7tm/. The rhodopsin-like GPCRs themselves represent a widespread protein family that includes hormone.eurotransmitter and light receptors.ll of which transduce extracellular signals through interaction with guanine nucleotide-binding (G) proteins. Although their activating ligands vary widely in structure and character.he amino acid sequences of the receptors are very similar and are believed to adopt a common structural framework comprising 7transmembrane (TM) helices .

The olfactory system is a highly-specialised chemical recognition systemthat.ike the immune system.s capable of discriminating with tremendoussensitivity between numerous foreign molecules in the environment.Olfactory transduction is believed to be initiated by the binding ofodorants to specific receptor proteins in the cilia of olfactory receptorcells. Although little is known about the precise mechanism by whichodorant binding might initiate membrane depolarisation.t is believedthat cyclic AMP may serve as an intracellular messenger for olfactorytransduction .The olfactory receptors are integral membrane proteins that belong to asuperfamily of G-protein-coupled receptors. The activating ligands of thedifferent superfamily members vary widely in structure and character.etthe proteins appear faithfully to have conserved a basic structural framework.elieved to consist of 7 transmembrane (TM) helices. Although thesequences of these proteins are very diverse.eflecting to some extentthis broad range of activating ligands.evertheless.otifs have beenidentified in the TM regions that are characteristic of virtually theentire superfamily . Amongst the exceptions are the olfactoryreceptors.hich cluster together in a subfamily that lacks significantmatches with domains 2. and 6 .
