Descriptions
Gαi1 is a G-protein alpha subunit that plays a crucial role in signal transduction pathway initiated by G-protein-coupled receptor (GPCR) activation. G proteins function as transducers downstream of GPCRs in numerous signaling cascades. The alpha subunit contains the guanine nucleotide binding site and alternates between an active (GTP-bound state) and an inactive (GDP-bound state). Activated GPCR induces conformational change in Gαi1, which allows for GDP-to-GTP exchange by binding to the GPCR-binding site within a Ras-like domain, leading to dissociation of the Gαi1 subunit and initiation of downstream signaling.
