Product Details

GUCY2C Effector Reporter Cell

I. Background

     鸟苷酸环化酶 C(GUCY2C/GCC)属于受体鸟苷酸环化酶(guanylyl cyclase,GC)家 族中的一员,该家族的酶能将 GTP 转化为第二信使 cGMP。GUCY2C 是一种在肠上皮细胞 顶膜上高表达的 I 型跨膜受体蛋白,该蛋白可作为内源性肽鸟苷蛋白和尿鸟苷蛋白以及耐 热大肠杆菌肠毒素的受体。GUCY2C 广泛表达于结直肠癌细胞和其他胃肠道肿瘤, GUCY2C 的功能丧失或增加与便秘或腹泻相关的几种疾病有关,包括肠易激综合征伴便秘 (IBS-C)和慢性特发性便秘(CIC)以及炎症性肠病(IBD)。

      GUCY2C 被内源性配体或外源性细菌毒素 STa 激活后,催化生成第二信使 cGMP,进 而通过激活囊性纤维化跨膜传导调节因子(CFTR)调控肠上皮细胞的离子和水分分泌,维持体液电解质平衡;同时该信号通路有助于维持肠道上皮屏障的完整性和抗炎作用,保护 肠道免受损伤。此外,GUCY2C 通过抑制 AKT 信号通路发挥肿瘤抑制因子的关键作用, 控制肠上皮细胞的增殖与代谢,从而抑制结直肠癌等肿瘤的发生。
