Anti-KEAP1 antibody produced in rabbit

产品说明

一般描述

The KEAP1 (kelch-like ECH-associated protein 1) gene encodes a protein containing an N-terminal BTB domain, a conserved linker domain, and a Kelch domain at the C-terminal. The gene is mapped to human chromosome 19p13.

免疫原

Kelch-like ECH-associated protein 1 recombinant protein epitope signature tag (PrEST)

应用

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.

生化/生理作用

The protein Keap1 (kelch-like ECH-associated protein 1) encoded by the gene KEAP1 negatively regulates Nrf2, a bZIP transcription factor involved in the induction of phase II detoxifying and oxidative stress enzyme genes, thus protecting cells from oxidative damage and maintaining cellular redox homeostasis. The encoded protein ubiquitinates Nrf2 by forming a functional E3 ubiquitin ligase complex with Cul3 and Rbx1. It increases the rate of proteasomal degradation of Nrf2 and also alters its subcellular distribution. Loss of keap1 function leads to increase in Nrf2 levels, which results in development of resistance to chemotherapeutic drugs in lung tumors. Mutations in this gene have been observed in NSCLC (Non-small-cell lung cancer).

特点和优势

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.
