Function
Keap1 is a 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. 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. 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. 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. The BCR(KEAP1) complex also mediates ubiquitination of SQSTM1/p62, increasing SQSTM1/p62 sequestering activity and degradation. The BCR(KEAP1) complex also targets BPTF and PGAM5 for ubiquitination and degradation by the proteasome[1][2][3][4][5][6][7][8][9][10][11][12][13][14].

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)
