- [Encoded by human GNAI3 Gene (G-Alpha 1 Family), 353-aa 40-kDa G(i) Alpha 3 Protein is a guanine nucleotide-binding alpha protein subunit of heterotrimeric G protein transducers (alpha, beta, gamma) in transmembrane signaling systems involved in hormonal regulation of adenylate cyclase. Containing virtually identical/similar beta and gamma chains, G proteins are most distinguished by alpha chains. G(i) proteins (alpha(i) subunit) inhibit cyclase in response to beta-adrenergic stimuli. Specific alpha chain regions appear to interact with guanine nucleotides, receptors, effector enzymes, and G protein beta-gamma complex. G proteins that inhibit adenylate kinase are substrates for pertussis toxin. GNAI3 is the stimulatory G protein of receptor-regulated K(+) channels.
