General annotation (Comments)
| 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. Ref.8 |
| Subunit structure | Heterodimer. Forms a ternary complex with PGAM5 and KEAP1. May bind DNA with an unknown protein. Interacts via its leucine-zipper domain with the coiled-coil domain of PMF1. Interacts with EEF1D at heat shock promoter elements (HSE). Ref.9 Ref.11 Ref.14 |
| Subcellular location | Cytoplasm › cytosol. Nucleus. Note: Cytosolic under unstressed conditions, translocates into the nucleus upon induction by electrophilic agents. Ref.8 Ref.15 |
| Tissue specificity | Widely expressed. Highest expression in adult muscle, kidney, lung, liver and in fetal muscle. |
| Induction | Down-regulated by ENC1 via a proteasomal ubiquitin-independent protein catabolic process. Ref.12 |
| Domain | Acidic activation domain in the N-terminus, and DNA binding domain in the C-terminus. |
| Post-translational modification | Phosphorylation of Ser-40 by PKC in response to oxidative stress dissociates NFE2L2 from its cytoplasmic inhibitor KEAP1, promoting its translocation into the nucleus By similarity. Acetylation at Lys-596 and Lys-599 increases nuclear localization whereas deacetylation by SIRT1 enhances cytoplasmic presence. Ubiquitinated by the KEAP1-CUL3-RBX1 E3 ubiquitin ligase complex and subject to proteasomal degradation. Ubiquitination is inhibited by sulforaphane. Ref.10 |
| Sequence similarities | Belongs to the bZIP family. CNC subfamily. Contains 1 bZIP (basic-leucine zipper) domain. |
| Sequence caution | The sequence AAB32188.1 differs from that shown. Reason: Erroneous initiation. The sequence BAD92023.1 differs from that shown. Reason: Erroneous initiation. |
