Olfactory receptors interact with odorant molecules in the nose, to initiate a neuronal response that triggers the perception of a smell. The olfactory receptor proteins are members of a large family of G-protein-coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a 7-transmembrane domain structure with many neurotransmitter and hormone receptors and are responsible for the recognition and G protein-mediated transduction of odorant signals. The olfactory receptor gene family is the largest in the genome. The nomenclature assigned to the olfactory receptor genes and proteins for this organism is independent of other organisms.

OR8A1 (Olfactory Receptor Family 8 Subfamily A Member 1) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and Olfactory transduction. Gene Ontology (GO) annotations related to this gene include G protein-coupled receptor activity and odorant binding. An important paralog of this gene is OR8D4.
