Olfactory receptor 52A1 is a protein that in humans is encoded by the OR52A1 gene.{{cite journal | vauthors = Feingold EA, Penny LA, Nienhuis AW, Forget BG | title = An olfactory receptor gene is located in the extended human beta-globin gene cluster and is expressed in erythroid cells | journal = Genomics | volume = 61 | issue = 1 | pages = 15–23 |date=Nov 1999 | pmid = 10512676 | doi = 10.1006/geno.1999.5935 | doi-access = free }}{{cite web | title = Entrez Gene: OR52A1 olfactory receptor, family 52, subfamily A, member 1| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=23538}}

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.{{cite web | title = Entrez Gene: OR52A1 olfactory receptor, family 52, subfamily A, member 1| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=23538}}
