Gene Information

human ... UTRN(7402)

General description

The gene utrophin (UTRN) is mapped to human chromosome 6q24. UTRN is an autosomal homologue of dystrophin. The protein contains an amino-terminal actin-binding domain, a central rod domain, a cysteine-rich domain and a carboxyl-terminal domain. UTRN is widely expressed, with high expression in non-skeletal muscle tissues including lung, intestine, embryonic neural tube, sensory ganglia, tendons and ossifying cartilages. UTRN is also present in the sarcolemma of fetal and regenerating muscle cells.

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

Utrophin (UTRN) interacts with sub-neuronal complex of proteins which include F-actin, dystrophin-associated proteins (DAPs), and the synapse-associated proteins rapsyn and agrin. The interaction is crucial for the maintenance of the post-synaptic membrane and clustering of acetylcholine receptors at the neuromuscular synapse. Overexpression of UTRN has been suggested as a potential approach for duchenne muscular dystrophy therapy.

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:
  • 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.


Corresponding Antigen APREST85175.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide.
