一般描述

毒晰外泌肽4是一种肠促胰岛素模拟肽，由39个氨基酸组成。它是胰高血糖素样肽1（GLP-1）类似物和促胰岛素分泌剂，半衰期长。最初从学名为钝尾毒蜥（Heloderma suspectum）的吉拉毒蜥的毒液中分离得到。

应用

毒晰外泌肽4可作为肠促胰岛素模拟物用于处理HepG2细胞，以排除辅助材料的影响。它也可用作r（GLP-1R）激动剂，以排除辅助材料的干扰。
毒晰外泌肽4可用于处理ob/ob小鼠模型，以确定葡萄糖和胰岛素的浓度以及内稳态评估模型（HOMA），还可用于测定毒晰外泌肽4处理的巨噬细胞中核因子-κΒ（NF-κB）p65水平。

生化/生理作用

可激活GLP-1（胰高血糖素样肽1）受体，增加胰腺腺泡细胞的细胞内cAMP； 对VIP受体没有作用。
毒晰外泌肽4模拟哺乳动物肠促胰岛素激素胰高血糖素样肽1（GLP-1）的活性，从而起到控制葡萄糖的作用。这包括以葡萄糖依赖性方式分泌胰岛素、高胰高血糖素分泌的负调节和胃排空持续时间的增加。在2型糖尿病患者体内，当二甲双胍作用不足时，可以皮下注射这种肽控制血糖。它可促进β-细胞的新生和增殖，从而有助于胰腺的再生。它是毒晰外泌肽受体的配体，还可导致腺泡细胞cAMP水平升高。

GLP-1-(7-36)-amide and exendin-4-(1-39) are glucagon-like peptide-1 (GLP-1) receptor agonists, whereas exendin-(9-39) is the only known antagonist. To analyze the transition from agonist to antagonist and to identify the amino acid residues involved in ligand activation of the GLP-1 receptor, we
