odr-4 encodes a novel type II membrane protein; ODR-4 is required for localization of a subset of G protein-coupled receptors (GPCRs)s, including ODR-10, to the cilia of olfactory neurons; ODR-4 affects response to a subset of AWA- and AWC- mediated olfactory responses, and is required for social feeding of npr-1 mutant animals; ODR-4 physically interacts with ODR-8 to form a complex at the endoplasmic reticulum membrane, and physically interacts wtih ODR-10, as well; ODR-4 is expressed in twelve pairs of chemosensory neurons: the ten amphid neurons and two phasmid neurons; odr-4 expression overlaps that of odr-8.
Involved in olfactory behavior; receptor localization to non-motile cilium; and response to odorant. Located in intracellular membrane-bounded organelle and protein-containing complex. Expressed in chemosensory neurons and neurons. Is an ortholog of human ODR4 (odr-4 GPCR localization factor homolog).
