Cytoglobin (CYGB) is a heme protein and belongs to the globin superfamily. It can be present in a number of states depending on the position and integrity of disulfide bonds. CYGB is expressed in the cytoplasm of mesenchymal fibroblastic cells and has a molecular mass of 21kDa. The gene encoding this protein is located on chromosome 17q25.
Synonyms: Anti-Cytoglobin; Anti-HGb; Anti-Histoglobin; Anti-Stellate cell activation-associated protein
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: Cytoglobin (CYGB) is down-regulated in tylosis with oesophageal cancer (TOC). The protein's heme co-ordination changes based on the lipids present in the surroundings and this in turn transforms the redox properties of the protein. CYGB may act as a marker to differentiate groups of cells in a damaged liver.
