Gucy2c

鸟苷酸环化酶C (guanylyl cyclase C,GUCY2C/GCC)属于受体鸟苷酸环化酶家族中的一员。该酶是细菌热稳定肠毒素的肠道受体,所以GUCY2C又称为热稳定肠毒素受体,主要参与调节肠道内水和电解质的平衡。在正常人机体组织中,GUCY2C主要表达于肠上皮细胞,在肠外组织和肿瘤中不表达。鸟苷素(guanylin,Gn)、尿鸟苷素(uroguanylin,Ugn)以及热稳定性肠毒素(heat-stable enterotoxin,STa)是GUCY2C的配体。当这些配体(Gn/Ugn/STa)与GUCY2C结合后,能激活GUCY2C,发挥生物学效应。GUCY2C主要与肠道疾病相关,以及较少报道的神经疾病。其中,肠道类相关的疾病主要包括功能性胃肠病(例如过敏性肠综合症,便秘,或酸度过量等)、炎症性肠病(例如克罗恩病和溃疡性结肠炎等)、癌症(例如胃肠道癌症)。针对GUCY2C这个靶点的肿瘤药物开发,已有国内上海斯丹赛生物技术有限公司的GUCY2C CAR-T 细胞疗法,以及辉瑞公司的GUCY2C-CD3双特异性抗体PF-0706119等等。
