Enables ionotropic olfactory receptor activity and ligand-gated monoatomic cation channel activity. Involved in monoatomic cation transmembrane transport; olfactory behavior; and sensory perception of smell. Located in dendrite membrane and sensory dendrite. Is expressed in adult olfactory antennal lobe glomerulus; large basiconic sensillum of antennal segment 3; organism subdivision; and sensory neurons.
FB Description
Odorant receptor 22a (Or22a) encodes a multi-transmembrane chemoreceptor that responds to ethyl butyrate. It localizes to dendritic membranes of neurons in the dorso-medial region of the antenna.
