Summaries for GNAI1 Gene

Entrez Gene Summary for GNAI1 Gene

  • Guanine nucleotide binding proteins are heterotrimeric signal-transducing molecules consisting of alpha, beta, and gamma subunits. The alpha subunit binds guanine nucleotide, can hydrolyze GTP, and can interact with other proteins. The protein encoded by this gene represents the alpha subunit of an inhibitory complex. The encoded protein is part of a complex that responds to beta-adrenergic signals by inhibiting adenylate cyclase. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

GeneCards Summary for GNAI1 Gene

GNAI1 (Guanine Nucleotide Binding Protein (G Protein), Alpha Inhibiting Activity Polypeptide 1) is a Protein Coding gene. Diseases associated with GNAI1 include pertussis. Among its related pathways are GPCR Pathway and Ras signaling pathway. GO annotations related to this gene include GTP binding and GTPase activity. An important paralog of this gene is GNAQ.

UniProtKB/Swiss-Prot for GNAI1 Gene

  • 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. The inactive GDP-bound form prevents the association of RGS14 with centrosomes and is required for the translocation of RGS14 from the cytoplasm to the plasma membrane. May play a role in cell division.

Tocris Summary for GNAI1 Gene

  • Heterotrimeric G proteins are membrane bound GTPases that are linked to 7-TM receptors. Each G protein contains an alpha-, beta- and gamma-subunit and is bound to GDP in the 'off' state. Ligand-receptor binding results in detachment of the G protein, switching it to an 'on' state and permitting Galpha activation of second messenger signalling cascades. There are several types of Galpha proteins; Galphas and Galphai bind directly to adenylyl cyclase and stimulate or inhibit its activity, leading to an increase or decrease in cAMP levels respectively.
