  • General notes

    NRF2 is bound to ubiquitin when it is the nucleus so MW would be higher than cytoplasm.

    WB protocol info included in legend for MDA-MB-231 nuclear extract treated with 30 µM tBHQ for 4 hours (+).

    Abcam recommended secondaries - Goat Anti-Rabbit HRP (ab205718) and Goat Anti-Rabbit Alexa Fluor® 488 (ab150077).

Target

  • Function
    Transcription activator that binds to antioxidant response (ARE) elements in the promoter regions of target genes. Important for the coordinated up-regulation of genes in response to oxidative stress. May be involved in the transcriptional activation of genes of the beta-globin cluster by mediating enhancer activity of hypersensitive site 2 of the beta-globin locus control region.
  • Tissue specificity
    Widely expressed. Highest expression in adult muscle, kidney, lung, liver and in fetal muscle.
  • Sequence similarities
    Belongs to the bZIP family. CNC subfamily.
    Contains 1 bZIP domain.
  • Domain
    Acidic activation domain in the N-terminus, and DNA binding domain in the C-terminus.
  • Post-translational
    modifications
    Phosphorylation of Ser-40 by PKC in response to oxidative stress dissociates NFE2L2 from its cytoplasmic inhibitor KEAP1, promoting its translocation into the nucleus.
  • Cellular localization
    Cytoplasm > cytosol. Nucleus. Cytosolic under unstressed conditions, translocates into the nucleus upon induction by electrophilic agents.

    ECL detection. 

  • ab137550 staining Nrf2 in HeLa cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with 4% paraformaldehyde. Samples were incubated with primary antibody diluted at 1/500 (green). Phalloidin, a cytoskeleton marker, diluted at 1/100 (red) was used.

  • ChIP was performed with HepG2 chromatin extract and 5 μg of either normal rabbit IgG or Anti-Nrf2 antibody (ab137550). The precipitated DNA was detected by PCR with primer set targeting to GCLC gene locus.

  • ab137550 staining Nrf2 in Rat liver tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/250 in BSA in TBS) for 30 minutes. A undiluted HRP-conjugated Goat anti-rabbit polyclonal was used as the secondary antibody.
