Gene Information

human ... HUWE1(10075)

General description

HUWE1 (HECT, UBA and WWE domain containing 1, E3 ubiquitin protein ligase) is an E3 ubiquitin ligase. It contains a region similar to the Bcl-2 homology region 3 (BH3) domain that interacts with Mcl-1 (myeloid cell leukemia 1).
HUWE1 is mapped on the human chromosome at Xp11.22. It has a molecular weight of 482 kDa.

Immunogen

E3 ubiquitin-protein ligase HUWE1 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.
Anti-HUWE1 antibody produced in rabbit has been used to promote hexokinase 2′s (HK2′s) K63- linked ubiquitination.

Biochem/physiol Actions

HUWE1 (HECT, UBA and WWE domain containing 1, E3 ubiquitin protein ligase) is essential for DNA damage-induced apoptosis. It plays an important role in the stimulation of Mcl-1 polyubiquitination and regulation of apoptosis. It can directly bind with p53 to ubiquitinate it. It is inactivated by ARF and inactivation is crucial for ARF (alternative reading frame)-mediated p53 stabilization. It polyubiquitinates Cdc6 (cell division cycle 6) in vitro which is an essential component of pre-replication complexes (preRCs) during initial phase of DNA replication. The polyubiquitination helps HUWE1 to control availability of Cdc6 in post DNA damage condition.
HUWE1 is involved in base excision repair, cell proliferation and DNA damage response. The mutation in this gene is associated with Juberg-Marsidi and Brooks syndromes.

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.

The elimination of Mcl-1, an anti-apoptotic Bcl-2 family member, is an early and required step for DNA damage-induced apoptosis. The degradation of Mcl-1 can be blocked by proteasome inhibitors, suggesting a role for the ubiquitin proteasome pathway in apoptosis. Here
