Guanylate cyclase-C receptor activation: unexpected biology.

Abstract excerpt

Guanylate cyclase-C (GC-C) is a transmembrane receptor activated by bacterial heat-stable enterotoxins and by the endogenous hormones guanylin and uroguanylin. GC-C plays key roles in the regulation of intestinal fluid and electrolyte homeostasis. This is highlighted by several recently identified human mutations in GUCY2C, the gene encoding GC-C, which leads to the respective gain or loss of function of GC-C,...
