  • Experimental Validation Results for Keap1 Antibody (YA324)
    Western blot analysis of extracts from RAW264.7 (lane 2(20μg), HepG2 (lane 3(20μg) and Hela (lane 4(20μg) using Keap1 (HY-P80732) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
  • Experimental Validation Results for Keap1 Antibody (YA324)
    Immunohistochemical analysis of paraffin-embedded Mouse kidney tissue using Keap1 Antibody. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 2 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HY-P80732, 1/100) in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background

  • Function

    Substrate-specific adapter of a BCR (BTB-CUL3-RBX1) E3 ubiquitin ligase complex that regulates the response to oxidative stress by targeting NFE2L2/NRF2 for ubiquitination (PubMed:14585973, PubMed:15379550, PubMed:15572695, PubMed:15601839, PubMed:15983046, PubMed:37339955). KEAP1 acts as a key sensor of oxidative and electrophilic stress: in normal conditions, the BCR(KEAP1) complex mediates ubiquitination and degradation of NFE2L2/NRF2, a transcription factor regulating expression of many cytoprotective genes (PubMed:15601839, PubMed:16006525). In response to oxidative stress, different electrophile metabolites trigger non-enzymatic covalent modifications of highly reactive cysteine residues in KEAP1, leading to inactivate the ubiquitin ligase activity of the BCR(KEAP1) complex, promoting NFE2L2/NRF2 nuclear accumulation and expression of phase II detoxifying enzymes (PubMed:16006525, PubMed:17127771, PubMed:18251510, PubMed:19489739, PubMed:29590092). In response to selective autophagy, KEAP1 is sequestered in inclusion bodies following its interaction with SQSTM1/p62, leading to inactivation of the BCR(KEAP1) complex and activation of NFE2L2/NRF2 (PubMed:20452972). The BCR(KEAP1) complex also mediates ubiquitination of SQSTM1/p62, increasing SQSTM1/p62 sequestering activity and degradation (PubMed:28380357). The BCR(KEAP1) complex also targets BPTF and PGAM5 for ubiquitination and degradation by the proteasome (PubMed:15379550, PubMed:17046835)

  • Subcellular Localization

    Cytoplasm; Nucleus

  • Expression


    Tissue_specificity:It is widely expressed, with the highest concentration in skeletal muscle.

  • Subunit

    Component of the BCR(KEAP1) E3 ubiquitin ligase complex, at least composed of 2 molecules of CUL3, 2 molecules of KEAP1, and RBX1 (PubMed:15572695, PubMed:15601839, PubMed:15983046, PubMed:17127771, PubMed:18251510, PubMed:24896564). Interacts with NFE2L2/NRF2; the interaction is direct (PubMed:15379550, PubMed:15601839, PubMed:16006525, PubMed:16888629, PubMed:18387606). Forms a ternary complex with NFE2L2/NRF2 and PGAM5 (PubMed:17046835). Interacts with (phosphorylated) SQSTM1/p62; the interaction is direct and inactivates the BCR(KEAP1) complex by sequestering it in inclusion bodies, promoting its degradation (PubMed:20452972, PubMed:20495340). Interacts with NFE2L1 (PubMed:16687406). Interacts with BPTF and PTMA (PubMed:15657435). Interacts with MAP1LC3B (PubMed:24089205). Interacts indirectly with ENC1 (PubMed:19424503). Interacts with SESN1 and SESN2 (PubMed:23274085). Interacts with HSP90AA1 and HSP90AB1 (PubMed:26517842). Interacts with PGCKA1; this interaction prevents the ubiquitination of KEAP1 by TRIM25, thus protecting KEAP1 from degradation (PubMed:36882524)
