BACKGROUND
Introduction Nucleobindin-2 (UniProt P80303; also known as DNA-binding protein NEFA, Epididymis secretory protein Li 109, Gastric cancer antigen Zg4, Nucleobinding 2, Prepronefastin, Prepronesfatin) is encoded by the NUCB2 gene (also known as HEL-S-109, NEFA) (Gene ID

Cleavage of signal peptide (aa1-24) yields the 396 aa mature nucleobindin-2 with very high sequence homology among human, mouse, and rat species (> 85%). Post-translational processing by prohormone convertases (PC 1/3 and PC 2) cleaves nucleobindin-2 into nesfatin-1, nesfatin-2, and nesfatin-3 (aa1–82, aa85–163, and aa166–396, respectively, numbering based on mature sequence). Nesfatin-1 is a well recognized circulating anorexigenic peptide, whose production increases post-prandially. Nucleobinin-2 contains two calcium-binding EF-hand domains separated by an acidic amino acid-rich region, and a leucine zipper. NUCB2 is expressed in key hypothalamic nuclei and plays a role in energy homeostasis. It is also expressed in various human peripheral tissues, including the stomach, pancreas, reproductive organs, and adipose tissue, suggesting its roles in various metabolic functions. NUCB2 expression level is reported to be elevated in clear cell renal cell carcinoma (ccRCC), breast cancer, and prostate cancer (PCa) tissues.
