G-Protein antagonist peptide acetate 是一种 substance P 相关肽，可抑制 G 蛋白与其受体的结合。G-Protein antagonist peptide acetate 竞争性和可逆性地抑制毒蕈碱型乙酰胆碱受体 M2 (M2 muscarinic receptor) 对 Gi 或 Go 的激活，并通过 β-肾上腺素受体抑制 Gs 的激活。

G-Protein antagonist peptide acetate is a truncated substance P-related peptide, competes with receptor for G protein binding. G-Protein antagonist peptide acetate inhibits the activation of Gi or Go by M2 muscarinic cholinergic receptor (M2 mAChR) or of Gs by beta-adrenergic receptor in the reconstituted phospholipid vesicles, assayed by receptor-promoted GTP hydrolysis
