Gene Information

General description
Itchy E3 ubiquitin protein ligase (ITCH) is characterized by an N- terminal protein kinase C-related C2 domain, four WW domains and a C-terminal homologous to the E6-associated protein carboxyl-terminus (HECT) ubiquitin protein ligase domain.
The gene ITCH (E3 ubiquitin-protein ligase Itchy homolog) is mapped to human chromosome 20q11.22. It belongs to Nedd4 (neural precursor cell expressed developmentally down-regulated protein 4) family of E3 ubiquitin ligases.
Immunogen
E3 ubiquitin-protein ligase Itchy homolog 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
ITCH (E3 ubiquitin-protein ligase Itchy homolog) is responsible for ubiquitination of CXCR4 (C-X-C chemokine receptor type 4) and ubiquitin binding protein Hrs (hepatocyte growth factor regulated tyrosine kinase substrate). ITCH also mediates ubiquitination of NF-E2 (nuclear factor, erythroid-derived 2) and thereby inhibits its transactivation function. Absence of ITCH leads to syndromic multisystem autoimmune disease.
Itchy E3 ubiquitin protein ligase (ITCH) in association with Ebola virus VP40 (eVP40), aids in virus-like particles (VLP) and virus budding. Overexpression of the gene is associated with the development of thyroid tumors, mainly anaplastic thyroid carcinoma (ATC).
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.

The hematopoietic-specific transcription factor p45/NF-E2 is an important transcriptional activator in the erythroid and megakaryocytic lineages. We describe the first in vivo evidence for the interaction between p45/NF-E2 and the E3 ubiquitin ligase Itch, and the subsequent ubiquitination of p45/NF-E2
