guanylin

Guanylin (mouse, rat), a peptide consisting of 15 amino acids, acts as an activator of intestinal guanylate cyclase and is utilized in diarrhea research [1].

Guanylin (human) TFA is a 15-amino acid peptide that serves as an endogenous activator of intestinal guanylate cyclase. This compound is primarily located in the gastrointestinal tract, where it regulates electrolyte and water transport in the intestinal and renal epithelia through a mechanism dependent on cyclic GMP. [1][2]

Endogenous peptide activator of intestinal guanylyl cyclase; secreted mainly by the gastrointestinal mucosa. Regulates water and electrolyte transport in intestinal and renal epithelia.

Uroguanylin-15 (Rat) is a bioactive natriuretic peptide hormone that modulates sodium excretion in response to high NaCl intake by activating guanylate cyclase signaling pathways in the intestine and kidney. Initially isolated from rat urine and duodenum, it shares functional similarities with guanylin but has not been detected in rat colon extracts.

Uroguanylin (human) serves as a natural ligand for the Guanylyl Cyclase C (GCC) receptor in metastatic colorectal cancer tumors and exhibits anti-tumor effects in an animal model of human colon cancer [1] [2].
