Or83b, also known as Orco (short for "odorant receptor co-receptor"), is an odorant receptor and the corresponding gene that encodes it.[1] 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.
