Gene Information

human ... UPF1(5976)

General description

The gene UPF1 (up-frameshift suppressor 1 homolog) is mapped to human chromosome 19p13.11. It belongs to the helicase superfamily 1. The protein localizes in the cytoplasm.


Regulator of nonsense transcripts 1 recombinant protein epitope signature tag (PrEST)


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

UPF1 (up-frameshift suppressor 1 homolog) regulates nonsense-mediated mRNA decay pathway and translation termination. It plays crucial role in degradation of histone mRNAs. Mutations in UPF1 are associated with pancreatic adenosquamous carcinoma.

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 APREST73937.

Physical form

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

Pancreatic adenosquamous carcinoma (ASC) is an enigmatic and aggressive tumor that has a worse prognosis and higher metastatic potential than its adenocarcinoma counterpart. Here we report that ASC tumors frequently harbor somatically acquired mutations in the UPF1 gene, which encodes...

Eukaryotic cells coordinately regulate histone and DNA synthesis. In mammalian cells, most of the regulation of histone synthesis occurs post-transcriptionally by regulating the concentrations of histone mRNA. As cells enter S phase, histone mRNA levels increase, and at the end...

Cellular mRNAs exist in messenger ribonucleoprotein (mRNP) complexes, which undergo transitions during the lifetime of the mRNAs and direct posttranscriptional gene regulation. A final posttranscriptional step in gene expression is the turnover of the mRNP, which involves degradation of the...

Nonsense-mediated decay (NMD) rids eukaryotic cells of aberrant mRNAs containing premature termination codons. These are discriminated from true termination codons by downstream cis-elements, such as exon-exon junctions. We describe three novel human proteins involved in NMD, hUpf2, hUpf3a, and hUpf3b....

Histone mRNAs are rapidly degraded at the end of S phase or when DNA replication is inhibited. Histone mRNAs end in a conserved stem-loop rather than a poly(A) tail. Degradation of histone mRNAs requires the stem-loop sequence, which binds the...
