Olfactory receptor family 4 subfamily P member 4 (OR4P4)

Olfactory receptor family 4 subfamily P member 4 (OR4P4) is a human G protein-coupled receptor involved in detecting odorant molecules in the nose, thereby initiating signal transduction for the sense of smell[1][3][5][10]. Like other olfactory receptors, it possesses a 7-transmembrane domain structure and is part of the largest gene family in the human genome[1][5]. OR4P4 is encoded by a single-exon gene on chromosome 11 and is not classified as a pseudogene; it is considered functional in humans[2][10]. Its primary biological role is in the olfactory pathway, with no established clinical significance beyond sensory perception, and it is not currently a drug development target or disease biomarker[5][10].
