The nuclear factor erythroid 2-related factor 2 (Nrf2) protein is a critical transcription factor for activating the antioxidant response pathway, a primary defense mechanism against disproportionate levels of oxidants in the cell, via the upregulation of cytoprotective genes. Notably, aberrant activation of Nrf2 in cancer cells increases their resistance to chemotherapy, rendering the treatment ineffective. The focus was to uncover the conformational landscape of Nrf2’s Neh4 and Neh5 domains, which participate in crucial interactions for complete transcriptional activation. Since Nrf2 is an intrinsically disordered protein (IDP), molecular dynamics simulations were employed to capture its dynamic nature and conformational heterogeneity. The …
