The function of OR2C1 (olfactory receptor family 2 subfamily C member 1, Ensembl gene identifier ENSG00000168158) is as follows. Olfactory receptor that is activated by the binding of organosulfur odorants with thioether groups such as (methylthio)methanetiol (MTMT) (By similarity). Also binds odorants acetophenone and benzaldehyde (By similarity). The activity of this receptor is mediated by G proteins which activate adenylyl cyclase (By similarity). May be involved in the molecular processes underlying fasciculation and targeting of olfactory axons (By similarity). .
