Appetite-Boosting Peptide Orexin-B is a linear 28-residue peptide. The mutual sequence similarity to Orexin-A is high, especially in their C-terminal regions. Human, rat and mouse peptide sequences have been determined and the primary structure of orexin-A is completely conserved among these species including bovine. Orexin B stimulates food intake in a dose-dependent manner (3/30 nmol) for a few hours with slight duration difference. In addition, hypothalamic orexin mRNA is found to be up-regulated in fasting. Orexin-B and A are coded tandemly in the same mRNA flanked by the double basic amino acid residues.The same mRNA was isolated by another group from rat hypothalamic mRNA clone; the putative reading frames corresponding to orexin-A and B are named hypocretin based on the sequence similarity to secretin.
