Odorant receptor which may be involved in sperm chemotaxis. Bourgeonal is a strong chemoattractant for sperm in vitro and is shown to be a strong agonist for OR1D2 in vitro. May also function in olfactory reception.
Subcellular locations: Cell membrane
In spermatazoa is localized in the midpiece and is translocated to the head region upon receptor stimulation with bourgeonal.
Expressed in testis. Expressed in spermatozoa (at protein level). Expressed in olfactory epithelium.
