Summary: Predicted to enable several functions, including G protein-coupled receptor binding activity; G-protein beta/gamma-subunit complex binding activity; and guanyl ribonucleotide binding activity. Predicted to be involved in several processes, including cellular response to forskolin; positive regulation of protein localization to cell cortex; and regulation of cAMP-mediated signaling. Predicted to be located in several cellular components, including centrosome; midbody; and nuclear lumen. Predicted to be part of heterotrimeric G-protein complex. Predicted to be active in cytoplasm. Is expressed in several structures, including early conceptus; forelimb; gut; nervous system; and reproductive system. Orthologous to human GNAI1 (G protein subunit alpha i1). [provided by Alliance of Genome Resources, Nov 2024]

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.
