基因資訊
human ... AATF(26574)
一般說明
Apoptosis antagonizing transcription factor (AATF) is a 73kDa nuclear phosphoprotein, which is made of 523 amino acids. Human AATF consists of a leucine zipper, many phosphorylation sites, putative nuclear localization signal- NLS1 and NLS2 and three motifs, which bind to nuclear receptors. The leucine zipper lies within residues 239- 260, and putative NLS within residues 300 and 467. AATF has an acidic N- terminal domain with two very acidic regions from residues 20-49 and 107-170, and these regions are separated by a Ser/Thr-rich domain. AATF is also known as Che-1, and in humans, it is located on chromosome 17q11.2-q12.
免疫原
Protein AATF recombinant protein epitope signature tag (PrEST)
應用
Anti-AATF antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
生化／生理作用
AATF was initially identified to interact with DAP like kinase (Dlk) and it interferes with Dlk- induced apoptosis. AATF has an essential role in the early steps of embryogenesis. It also interacts with transcription factors as an adaptor to promote transcription. AATF is activated by ER (endoplasmic reticulum) stress through PERK signalling, which in turn activates v-akt murine thymoma viral oncogene homolog 1 (AKT1) via STAT3, leading to cell survival and cell resistance to ER stress. AATF and Wolfram syndrome 1 (WFS1) genes have also been shown to crosstalk, and therefore deficiencies in either gene mediate apoptosis in Wolfram syndrome. AATF might also act as a neuroprotective agent as its suppression by Aβ protein in cortical neuronal cells increases Aβ toxicity in these cells. AATF also interacts with Par-4 (prostate apoptosis response-4) and prevents the aberrant production of Aβ-42 peptide by Par-4.
特點和優勢
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.
