Gene Information
human ... OCLN(4950)
General description
Occludin (OCLN) is an important membrane protein that is localized in the tight junction (TJ). This protein is made up of four transmembrane proteins, a short N-terminal cytoplasmic domain, two extracellular loops, one intracellular turn, and a long C-terminal cytoplasmic domain. Occludin is expressed in the endothelial and epithelial cells of TJs. OCLN gene is mapped on the human chromosome at 5q13.2.

Occludin recombinant protein epitope signature tag (PrEST)
Application
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project 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. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions
Occludin (OCLN) is involved in maintaining the integrity of the blood-brain barrier (BBB). Degradation of occludin may increase the permeability of the BBB, observed in several central nervous system disorders such as ischemic stroke. Mutations in the OCLN gene lead to the progression of human breast cancer. Mutations in this gene are also associated with brain calcification and chronic kidney disease in children. Mutations in the OCLN gene can also cause bilateral band-like calcification with polymicrogyria (BLC-PMG).
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:
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.

Pediatric intracranial calcification may be caused by inherited or acquired factors. We describe the identification of a novel rearrangement in which a downstream pseudogene translocates into exon 9 of OCLN, resulting in band-like brain calcification and advanced chronic kidney disease
