Type A Allatostatin I is a tridecapeptide. Allatostatins are pleiotropic neuropeptides for inhibition of juvenile hormone synthesis in insects.

Potent endogenous ligand of the kisspeptin receptor (KISS1, GPR54). Binds with high affinity to rat and human KISS1 receptors with Ki values of 1.80 and 1.45 nM respectively. Inhibits chemotaxis, invasion and metastasis of human melanomas and breast carcinomas. Stimulates gonadotropin secretion following i.c.v. administration.

Calcitonin (8-32), salmon is a highly selective amylin receptor antagonist.Calcitonin is a hormone known to participate in calcium and phosphorus metabolism. In mammals, the major source of calcitonin is from the parafollicular or C cells in the thyroid gland. Calcitonin is a 32 amino acid peptide cleaved from a larger prohormone.
