Guanine Nucleotide-Binding Protein G(i) Subunit Alpha-1

**Semantic type:** Amino Acid, Peptide, or Protein

**Definition:** Guanine nucleotide-binding protein G(i) subunit alpha-1 (354 aa, ~40 kDa) is encoded by the human GNAI1 gene. This protein may play a role in signal transduction by inhibiting adenylate cyclase in response to beta-adrenergic stimuli.

**Synonyms:** - Adenylate Cyclase-Inhibiting G Alpha Protein - G Protein Alpha Inhibiting Activity Polypeptide 1 - G(i) Alpha 1 Protein - GNAI1 - Gi1 Protein Alpha Subunit - Guanine Nucleotide Binding Protein Alpha Inhibiting Activity Polypeptide 1 - Guanine Nucleotide Binding Protein G(i), Alpha-1 Subunit
