WebJun 1, 2024 · NFE2L2 mutations occur exclusively in an exon 2 hotspot that encodes the Neh2 domain (aa.1-86), which is the binding site for Keap1. Mutations in this region disrupt Keap1 binding, leading to Nrf2 nuclear translocation and increased mTOR signaling through regulation of RagD (Shibata Cancer Res 2010). WebJul 5, 2024 · From previous work, our group found that low glutamate levels are a hallmark of KEAP1-mutant tumors, which become very dependent on nutrients such as glutamine. Until recently, there was no good way to target glutamine or other glutamine-consuming enzymes in tumor cells.
