The gene GPA33 (cell surface A33 antigen) is mapped to human chromosome 1q24.1. GPA33 is a membrane-associated glycoprotein. The protein is present in the small intestine and colonic epithelium.
Synonyms: GPA33 Antibody - Anti-GPA33 antibody produced in rabbit; Gpa33 Antibody; A33; Glycoprotein A33
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: Cell surface A33 antigen (GPA33) is uniformly expressed in colorectal cancers. Gut-enriched Krüppel-like factor (GKLF) associates with the promoter of GPA33 and thereby induces its expression in intestinal epithelium.
