About GNAI2

Cytogenetic location: 3p21.31 Genomic coordinates (GRCh38): 3:50,227,068-50,263,358 (from NCBI)

This gene has 12 transcripts (splice variants), 292 orthologues, 15 paralogues and is associated with 1 phenotype. Ubiquitous expression in spleen (RPKM 106.7), bone marrow (RPKM 93.2) and 25 other tissues.

Summary

The protein encoded by this gene is an alpha subunit of guanine nucleotide binding proteins (G proteins). The encoded protein contains the guanine nucleotide binding site and is involved in the hormonal regulation of Adenylate Cyclase. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2013]
