Neuronostatin, a bioactive peptide hormone, was encoded by pro-somatostatin and discovered using a bioinformatic method in 2008. Neuronostatin is widely expressed in the central nervous system (CNS) and peripheral tissues, it is also highly conserved among humans, rodents, and even goldfish. The 13 and 19 amino acids and the C-terminal amidation type play important roles in physiological and pathological functions. The present study reviews the roles of neuronostatin in food intake and drinking of water, as well as in the neuroendocrine processes, pain regulation, cardiovascular and circulation function, memory and studies, depression-like effect, and energy metabolism in animals. However, the information on the physiology and pathology of neuronostatin, especially the molecular mechanism, remains scarce. Considering the broad functions of neuronostatin, this endogenous neuropeptide could be a promising therapeutic target for future research and drug design if the exact receptor could be found in humans.
