|Protein Name||Kelch-like ECH-associated protein 1|
|Molecular Weight||69666 MW|
|Protein Function||Acts as a substrate adapter protein for the E3 ubiquitin ligase complex formed by CUL3 and RBX1 and 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. Retains NFE2L2/NRF2 and may also retain BPTF in the cytosol. Targets PGAM5 for ubiquitination and degradation by the proteasome. .|
|Tissue Specificity||Broadly expressed, with highest levels in skeletal muscle. .|
|Sequence Similarities||Contains 1 BACK (BTB/Kelch associated) domain.|
|Subcellular Localization||Cytoplasm. Nucleus. Shuttles between cytoplasm and nucleus.|
|Alternative Names||Kelch-like ECH-associated protein 1;Cytosolic inhibitor of Nrf2;INrf2;Kelch-like protein 19;KEAP1;INRF2, KIAA0132, KLHL19;|
|Research Areas|||epigenetics and nuclear signaling|chromatin modifying enzymes|ubiquitylation||

1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected
2. Post-translational cleavage: this can cause smaller bands and or multiple bands
3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody.
4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.
5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher.,
