Or83b Odorant receptor : ウィキペディア英語版 | Or83b Odorant receptor
Or83b is an odorant receptor and the corresponding gene that encodes it. The odorant receptor Or83b is not exclusively expressed in insects. Though its actual function is still a mystery, the broadly expressed Or83b has been conserved across highly divergent insect populations across 250 million years of evolution. ==Function of Or83b== There are two contending models for potentially explaining Or83b function. One proposes are that it could interact with specific odor stimuli independently of other odorant receptors (ORs). The other proposes that it could act with other ORs to mediate responses to all odors. Or83b mutation disrupts behavioral and electrophysiological responses to many odorants, which supports the second model that OR plays a general rather than specific role in olfaction. When mutating the Or83b gene, larval Drosophila do not travel towards an area of ethyl acetate which is an important odorant related to rotting fruit ().
