Supplementary information

The protein GNAI1 also known as G protein subunit alpha i1 is part of the G-protein family that plays an important role in signal transduction. GNAI1 has a molecular mass of approximately 40 kDa. It is mainly expressed in neuronal tissues where it interacts with receptors to regulate intracellular signaling pathways. This protein operates by inhibiting adenylate cyclase activity which reduces the production of cyclic AMP (cAMP) in response to extracellular signals.
Biological function summary

GNAI1 acts by interfering with signal transmission across membranes. It is part of the heterotrimeric G-protein complex which is essential for many signaling processes. This complex responds to activation by G-protein-coupled receptors (GPCRs) and modulates various downstream effectors essentially affecting numerous physiological processes like neurotransmission and hormone signaling.

Pathways

GNAI1 plays a significant role in the cyclic AMP (cAMP) signaling pathway and the neuroactive ligand-receptor interaction pathway. In the cAMP pathway GNAI1 associates with receptors like dopamine and serotonin receptors helping to regulate neuronal response and neurotransmitter release. This activity involves interactions with related proteins such as GNB1 and GNG2 which form the beta and gamma subunits of the heterotrimeric G-protein complex.

GNAI1 relates to neuropathic conditions such as epilepsy and depression. Alterations in GNAI1 function can disrupt normal signaling contributing to these disorders. The protein interacts with other proteins in the signaling cascade such as RGS proteins which can affect its function in disease states. Researchers continue to explore how modifications or mutations in GNAI1 might offer potential therapeutic targets for these and similar disorders.

Target data

Guanine nucleotide-binding proteins (G proteins) function as transducers downstream of G protein-coupled receptors (GPCRs) in numerous signaling cascades (PubMed : 18434541, PubMed : 33762731, PubMed : 34239069, PubMed : 35610220, PubMed : 37935376, PubMed : 37935377, PubMed : 37963465, PubMed : 38552625, PubMed : 8774883). The alpha chain contains the guanine nucleotide binding site and alternates between an active, GTP-bound state and an inactive, GDP-bound state (PubMed : 18434541, PubMed : 8774883). Signaling by an activated GPCR promotes GDP release and GTP binding (PubMed : 18434541, PubMed : 8774883). The alpha subunit has a low GTPase activity that converts bound GTP to GDP, thereby terminating the signal (PubMed : 18434541, PubMed : 8774883). Both GDP release and GTP hydrolysis are modulated by numerous regulatory proteins (PubMed : 18434541, PubMed : 8774883). Signaling is mediated via effector proteins, such as adenylate cyclase : inhibits adenylate cyclase activity of ADCY1, ADCY5 and ADCY6, leading to decreased intracellular cAMP levels (PubMed : 8119955). 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. Required for normal cytokinesis during mitosis (PubMed : 17635935). Required for cortical dynein-dynactin complex recruitment during metaphase (PubMed : 22327364).
