Anti-G protein/Gαβγ Recombinant Antibody|抗G蛋白/Gαβγ重组抗体(靶标：G蛋白αβγ异源三聚体)

Guanine nucleotide-binding protein G(s) subunit alpha isoforms short (Gαβγ) is a ~45 kDa protein. Guanine nucleotide-binding proteins (G proteins) function as transducers in numerous signaling pathways controlled by G protein-coupled receptors (GPCRs). The alpha chain contains the guanine nucleotide binding site and alternates between an active, GTP-bound state and an inactive, GDP-bound state. Signaling by an activated GPCR promotes GDP release and GTP binding. The alpha subunit has a low GTPase activity that converts bound GTP to GDP, thereby terminating the signal. Both GDP release and GTP hydrolysis are modulated by numerous regulatory proteins.
