Preparation and Storage

Background: Nesfatin-1/Nucleobindin-2

Nesfatin-1 (NEFA Encoded Satiety and Fat-influencing protein 1) is a presumably secreted peptide derived from the translation product of the NUCB2 gene. Nesfatin‑1 is associated with neurons involved in feeding (ARH and PVH), fluid intake (SON and PVH) and autonomic activity, in beta -cells of the pancreas, endocrine cells in the stomach, and in adipocytes. Its presence peripherally has an anorexigenic effect. Mature rat Nesfatin-1 is 82 amino acids (aa) in length. Although it is 10 kDa in MW, its presence in SDS-PAGE is difficult to detect in biological fluids. It represents the N-terminal cleavage product of a 420 aa precursor termed NEFA/Nucleobindin‑2/NUCB2. NUCB2 contains a signal sequence (aa 1-24), Nesfatin-1 (aa 25-106), a DNA-binding site (aa 171-223), and two EF-hand regions (aa 241-276 and 293-328). Full-length NUCB2 is 48-55 kDa in size, and may be present extracellularly. There is a potential for multiple cleavages that would generate Nesfatin-1, Nesfatin-2 (aa 109-187) and Nesfatin-3 (aa 190-420). A 25 kDa peptide that represents Nesfatin-1 and -2 has been reported. Rat Nesfatin-1 (aa 25-106) shares 97% and 84% aa identity with mouse and human Nesfatin-1, respectively.
