Predicted to enable G protein-coupled receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and GTPase activity. Predicted to be involved in adenylate cyclase-modulating G protein-coupled receptor signaling pathway. Located in non-motile cilium. Expressed in several structures, including P lineage cell; body wall musculature; neurons; somatic gonad; and vulval precursor cell. Human ortholog(s) of this gene implicated in achromatopsia 4; congenital stationary night blindness 1G; and congenital stationary night blindness autosomal dominant 3. Is an ortholog of human GNAI1 (G protein subunit alpha
i1).
