Our Abpromise guarantee covers the use of ab118285 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.2 - 0.6 µg/ml. Detects a band of approximately 75 kDa (predicted molecular weight: 70 kDa).
IHC-P Use a concentration of 3 - 5 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • FunctionRetains NFE2L2/NRF2 in the cytosol. Functions as substrate adapter protein for the E3 ubiquitin ligase complex formed by CUL3 and RBX1. Targets NFE2L2/NRF2 for ubiquitination and degradation by the proteasome, thus resulting in the suppression of its transcriptional activity and the repression of antioxidant response element-mediated detoxifying enzyme gene expression. May also retain BPTF in the cytosol. Targets PGAM5 for ubiquitination and degradation by the proteasome.
  • Tissue specificityBroadly expressed, with highest levels in skeletal muscle.
  • Sequence similaritiesContains 1 BACK (BTB/Kelch associated) domain.
    Contains 1 BTB (POZ) domain.
    Contains 6 Kelch repeats.
  • DomainThe Kelch repeats mediate interaction with NF2L2/NRF2, BPTF and PGAM5.
  • Post-translational
    Ubiquitinated and subject to proteasomal degradation.
  • Cellular localizationCytoplasm. Nucleus. Shuttles between cytoplasm and nucleus.
