Amylin (rat, mouse) (trifluoroacetate salt)

Amylin is a 37-residue peptide hormone secreted by pancreatic beta-cells that reduces food intake, modifies glycogen synthesis, slows gastric emptying, and increases satiety. It binds to heteromeric complexes of human calcitonin receptor 2 (CTR2) with receptor activity-modifying protein (RAMP) 1 or 3 (IC50s = 7.86 and 6.35 nM, respectively). It also binds to mouse alpha-thyroid-stimulating hormone thyrotroph (alpha-TSH) cells (IC50 = 10.5 nM) and rat nucleus accumbens membrane preparations (Ki = 0.024 nM). In vitro, amylin (100 nM) inhibits insulin-induced, but not basal, glycogen synthesis in hepatocytes isolated from fasted rats. It also inhibits insulin-induced glycogen synthesis ex vivo in isolated soleus muscle from fasted rats. In vivo, amylin delays gastric emptying in rats (ED50 = 69 pmol) and decreases food intake in fasted mice (ED50 = 110 µg/kg). Unlike human amylin (Cay-24274), rat amylin does not form fibrils and is not cytotoxic.Formal Name: L-lysyl-L-cysteinyl-L-asparaginyl-L-threonyl-L-alanyl-L-threonyl-L-cysteinyl-L-alanyl-L-threonyl-L-glutaminyl-L-arginyl-L-leucyl-L-alanyl-L-asparaginyl-L-phenylalanyl-L-leucyl-L-valyl-L-arginyl-L-seryl-L-seryl-L-asparaginyl-L-asparaginyl-L-leucylglycyl-L-prolyl-L-valyl-L-leucyl-L-prolyl-L-prolyl-L-threonyl-L-asparaginyl-L-valylglycyl-L-seryl-L-asparaginyl-L-threonyl-L-tyrosinamide, cyclic (2->7)-disulfide, trifluoroacetate salt.
