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.
Synonyms: Anti-DNA-binding protein NEFA; Anti-Gastric cancer antigen Zg4; Anti-Nucleobindin-2 precursor
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

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.
