Recombinant Human Guanine nucleotide-binding protein G (i) subunit alpha-2 (GNAI2)

Uniprot Id

P04899

Target Species

Human

Target Name

GNAI2

Target Full Name

Guanine nucleotide-binding protein G(i) subunit alpha-2

Target Function

Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. The G(i) proteins are involved in hormonal regulation of adenylate cyclase: they inhibit the cyclase in response to beta-adrenergic stimuli. May play a role in cell division.; Regulates the cell surface density of dopamine receptors DRD2 by sequestrating them as an intracellular pool.

Target Subcellular Location

Cytoplasm. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Cell membrane. Membrane; Lipid-anchor. Note=Localizes in the centrosomes of interphase and mitotic cells. Detected at the cleavage furrow and/or the midbody.

Target Protein Families

G-alpha family, G(i/o/t/z) subfamily

Target Background

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.
