Neuropeptides control a wide spectrum of physiological functions. They are central to our understanding of brain functions. They exert their actions by interacting with specific G protein-coupled receptors. We however have not found all the neuropeptides that exist in organisms. The search for novel neuropeptides is thus of great interest as it will lead to a better understanding of brain function and disorders. In this review, we will discuss the historical as well as the current approaches to neuropeptide discovery, with a particular emphasis on the orphan GPCR-based strategies. We will also discuss two novel peptides, neuropeptide S and neuromedin S, as examples of the impact of neuropeptide discovery on our understanding of brain functions. Finally, the challenges facing neuropeptide discovery will be discussed.
