Melanin Concentrating Hormone (MCH), a 19 amino acid cyclic peptide, is largely expressed in the hypothalamus. Melanin Concentrating Hormone is implicated in the control of general arousal and goal-orientated behaviours in mammals, and appears to be a key messenger in the regulation of food intake.

(Pro30,Tyr32,Leu34)-Neuropeptide Y (28-36)

Gp100 (25-33), human is the amino acids 25-33 fragment of the human melanoma antigen. It is a 9-amino acid (AA) epitope restricted by H-2Db and recognized by the T cells.This is amino acids 25 to 33 fragment of human melanoma antigen gp100. This H-2Db restricted epitope is recognized by T cells. The gp100-specific, H-2Db-restricted, CD8+ T cells are capable of recognizing B16 melanoma but not normal melanocytes.
