Gnai3 - G protein subunit alpha i3

Enables G protein-coupled serotonin receptor binding activity; GTPase activating protein binding activity; and protein domain specific binding activity. Involved in several processes, including positive regulation of NAD(P)H oxidase activity; positive regulation of superoxide anion generation; and positive regulation of vascular associated smooth muscle cell proliferation. Located in membrane raft; plasma membrane; and zymogen granule. Biomarker of hypertension. Orthologous to human GNAI3 (G protein subunit alpha i3). [provided by Alliance of Genome Resources, Apr 2022]
