Background: Guanylyl Cyclase C/GUCY2C

Guanylyl Cyclase C (GUCY2C), also known as heat-stable enterotoxin receptor, is a type I transmembrane protein of the guanylate cyclase (GC) family expressed by intestinal epithelial cells from the duodenum to rectum. It was first identified as the intestinal epithelial receptor regulating fluid and electrolyte transport in the secretory diarrhea induced by bacterial enterotoxins (1). There are 7 known members of the GC family (GC-A through GC-G) and they catalyze the conversion of guanosine triphosphate to cyclic guanosine monophosphate (cGMP) and pyrophosphate (2-4). Mature mouse GUCY2C consists of an extracellular domain (ECD) with a ligand binding domain, a transmembrane segment and a cytoplasmic region possessing a kinase and GC catalytic domain. The ECD of mouse GUCY2C shares 70% and 88% amino acid sequence identity with the ECD of human and rat GUCY2C, respectively. Endogenous ligands of GUCY2C include guanylin and uroguanylin (5). GUCY2C in epithelial cells plays an important role in cell dynamics and homeostatic balance of proliferation, metabolism, and differentiation that organizes the guanylyl cyclase C hormone axis. GUCY2C is also expressed in the brain and is implicated in attention deficiency and hyperactive behavior (5-7).
