Gene Information

human ... NUCB2(4925)

General description

Nucleobindin 2 (NUCB2) is a Ca2+-binding leucine zipper-containing protein. It is located in the Golgi apparatus and belongs to the nucleobindin family of DNA- and calcium-binding proteins. NUCB2 contains helix-loop-helix domains.


Nucleobindin-2 precursor recombinant protein epitope signature tag (PrEST)

Biochem/physiol Actions

Nucleobindin 2 (NUCB2) along with aminopeptidase 1 (ARTS-1) regulates tumor necrosis factor receptor 1 (TNFR1) release to the extracellular space. The helix-loop-helix domain of NUCB2 binds to the extracellular domain of ARTS-1. This results in the formation of a calcium-dependent NUCB2-ARTS-1 complex which associates with TNFR1. TNFR1is released in the form of exosome-like vesicles.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.


Corresponding Antigen APREST70301.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
