Tyr-Uroguanylin (rat)

Tyr-Uroguanylin (rat) is a high-purity synthetic peptide representing an N-terminal tyrosine-modified form of rat uroguanylin. This 16-amino acid peptide retains the biological activity of native uroguanylin while incorporating a tyrosine residue at the N-terminus, which facilitates radiolabeling, detection, and enhanced solubility properties. Manufactured under stringent quality controls with HPLC-verified purity and comprehensive analytical documentation, this product provides researchers with a versatile tool for studying guanylate cyclase-C (GC-C) receptor signaling, gastrointestinal physiology, and renal function. The tyrosine modification enables applications in receptor binding assays, competitive inhibition studies, and detection-based experiments, making it particularly valuable for quantitative and analytical research approaches.

1.MECHANISM OF ACTION

Tyr-Uroguanylin (rat) functions as a guanylate cyclase-C (GC-C) receptor agonist, binding to the extracellular domain of GC-C receptors expressed on intestinal and renal epithelial cells. This binding activates the intracellular catalytic domain, leading to the conversion of GTP to cyclic GMP (cGMP). The elevated intracellular cGMP levels activate protein kinase G (PKG), which phosphorylates downstream effectors including the cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel. This signaling cascade stimulates chloride and bicarbonate secretion while inhibiting sodium absorption, ultimately regulating fluid and electrolyte transport. The N-terminal tyrosine modification does not significantly alter the peptide's receptor-binding affinity or biological activity, allowing it to function similarly to native uroguanylin while providing additional utility for detection and labeling applications.
