产品描述 | Guanylin is a peptide hormone activator of membrane-bound guanylate cyclase C (GC-C).1,2It contains four cysteines that can form disulfide bridges leading to two possible isoforms, with the active form containing disulfide bridges between Cys4and Cys12and Cys7and Cys15.1Guanylin is found in epithelial cells of the small intestine where it activates GC-C to increase intestinal chloride and fluid secretion.2,3,4Guanylin expression is reduced by 100- to 1,000-fold in greater than 85% of isolated tumors from patients with colorectal cancer compared with adjacent non-cancerous intestinal epithelial tissue.5 1.Nokihara, K., Wray, V., Ando, E., et al.Synthesis, solution structure, binding activity, and cGMP activation of human guanylin and its disulfide isomerRegul.
