Primary citation

Orexin-A is composed of a highly conserved C-terminal and a specific, hydrophilic N-terminal region, revealing the structural basis of specific recognition by the orexin-1 receptor. Takai, T., Takaya, T., Nakano, M. et al. J Pept Sci (2006) 12:443-454. DOI 10.1002/psc.747 · PubMed
