Synonyms: SCG1
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: CHGB (chromogranin B) plays an essential role in the synthesis of secretory vesicles. In neuroendocrine system, it has both intracellular and extracellular roles. It plays an essential role in neuroendocrine/sympathoadrenal stress response to systemic infection, where it cleaves chromaffin granule proteins at dibasic sites to produce smaller peptides. It is also responsible for the sorting and transport of peptide hormones and neuropeptide precursors to secretory granules. This, is turn, might be responsible for initiating the synthesis of secretory granules. Variants of this gene are linked with isoprostane formation, which is linked with oxidative stress. Polymorphisms in this gene are also associated with increased susceptibility and onset of amyotrophic lateral sclerosis (ALS), where abnormalities in secretory pathway might lead to elevated vulnerability of motor neurons.
