Description

General description

A decapeptide with C-terminally amidated LRF-motif that acts as a potent and selective agonist of AXOR12 and hOT7T175 (a novel human G-protein-coupled receptors). Induces an increase in intracellular Ca²⁺ levels in CHO/h175 and CHO/AXOR12:Gqi5 cells and exhibits about 8-fold higher receptor binding affinity (K_i = 42 pM) compared to Metastin (Cat. No. 445885).
