Product Description

Rabbit anti Human Keap1 Antibody, Recombinant, could be used for WB, IHC and so on.
Application:
WB: 1/500 - 1/1000
IHC : 1/50 - 1/100
Protein Function
Retains 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.
Post-translational
Ubiquitinated and subject to proteasomal degradation.
