1.MECHANISM OF ACTION

Urotensin II (Goby) exerts its biological effects through a mechanism highly consistent with its homolog, Frog neuropeptide—via high-affinity binding to the urotensin II receptor (UT), a G-protein-coupled receptor (GPCR) widely expressed in goby vascular tissues, cardiovascular organs, and the central nervous system. The peptide’s conserved sequence (homologous to Frog neuropeptide) and dual disulfide bonds optimize conformational stability, ensuring high selectivity and affinity for goby UT receptors, while enabling cross-species comparative analysis with Frog neuropeptide.

2.PRODUCT INDICATIONS

UT receptor research: Investigation of UT receptor structure-function relationships in goby models, serving as a standard ligand for activation assays, agonist/antagonist screening, and comparative binding analysis with Frog neuropeptide.

Fish physiology research: Study of vascular tone regulation, cardiovascular function, and osmotic balance in gobies, supporting exploration of fish-specific physiological mechanisms.

Comparative neuropeptide research: Analysis of structural and functional homology between goby urotensin II and Frog neuropeptide, aiding evolutionary biology and cross-species neuropeptide studies.

3.CLINICAL EFFICACY OF PRODUCT

Urotensin II (Goby) is widely utilized in fish-focused preclinical research, with proven efficacy in both in vitro and in vivo goby models, and high comparability to Frog neuropeptide. In goby vascular smooth muscle cell assays, it exhibits potent UT receptor activation—consistent with the activity profile of Frog neuropeptide—effectively modulating contraction/relaxation responses with sustained activity due to intact disulfide bonds, ensuring reliable experimental results.
