odr-3 encodes a G protein alpha subunit; odr-3 activity is required for normal chemotaxis, odorant avoidance, and nociceptive function as well as cilium morphogenesis in chemosensory neurons; an ODR-3::GFP is expressed in five pairs of sensory neurons AWA, AWB, AWC, ASH, and ADF; the AWC neurons consistently express GFP most strongly, while the AWB neurons express at lower levels and the AWA, ASH, and ADF neurons express only weakly; in AWC neurons, ODR-3::GFP localizes to cilia which have a characteristic wing-shaped morphology.
Enables olfactory receptor binding activity. Involved in several processes, including hyperosmotic response; olfactory behavior; and response to odorant. Located in neuronal cell body and non-motile cilium. Expressed in amphid neurons.
