Predicted to enable several functions, including G-protein beta/gamma-subunit complex binding activity; GTPase activity; and guanyl ribonucleotide binding activity. Involved in embryonic axis specification and establishment of mitotic spindle orientation. Located in cell cortex. Expressed in several structures, including Psub4; Z2; Z3; neurons; and pharynx. 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).
