    Summary
    Predicted to enable G protein-coupled receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and GTPase activity. Involved in several processes, including G protein-coupled receptor signaling pathway; negative regulation of cell communication; and positive regulation of cell population proliferation. Located in plasma membrane. Used to study hypertension. Biomarker of cardiomyopathy and hypertension. Orthologous to human GNAI2 (G protein subunit alpha i2).

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
