Anti-NUCB2 (N-terminal) antibody produced in rabbit

NUCB2 (N-terminal) (nucleobindin 2, also known as NEFA, p54) belongs to the nucleobindin family of EF-hand Ca²⁺-binding proteins.

Nucleobindin 2 (NUCB2), contain multiple functional domains, including a Leu/Ile-rich region, a putative nuclear localization signal, a DNA binding domain, two Ca²⁺ -binding EF-hand motifs, and a leucine zipper region. NUCB2 is widely distributed and is localized to the Golgi apparatus. Human NUCB2 has high homology (62% sequence identity) with human NUCB1, an additional member of the nucleobindin family, although they are encoded by two separate genes.

Anti-NUCB2 (N-terminal) antibody produced in rabbit has been used in:

• immunofluorescence
• western blotting
• immunohistochemistry

Nucleobindin 2 (NUCB2) is implicated in various functions, including Ca²⁺ homeostasis, hypothalamic regulation of feeding, and tumor necrosis factor (TNF)-receptor-1 (TNFR1) shedding. NUCB2 has been shown to interact with both necdin and endoplasmic reticulum aminopeptidase 1 (ARTS-1), both through the EF-hand motif. NUCB2-ARTS-1 complex is required for the proteolytic cleavage and release of TNFR1 to the extracellular compartment. NUCB2 has been recently identified as a novel satiety molecule in the hypothalamus, associated with melanocortin signaling in the central nervous system. NUCB2 and its N-terminal 82-amino acid cleavage fragment, termed nesfatin-1, have been shown to induce suppression of food-intake in rats.
