Biophysical investigation of the molecular interaction between minichromosome maintenance protein 6 and Bloom syndrome helicase.

ABSTRACT: The minichromosome maintenance protein (MCM) complex and Bloom syndrome helicase (BLM) are crucial components in DNA replication and cell division. MCM, a hexameric helicase that unwinds double-stranded DNA, serves as an important diagnostic and prognostic biomarker for cancer cells and a target for anticancer drug development. BLM, associated with G-quadruplex structures, is another key helicase in maintaining genomic stability. In this study, we investigate the interaction between MCM6 and BLM at the atomic level, as their expression levels are highly correlated in various cancer types, with elevated levels indicating poor prognosis. To elucidate the molecular basis of MCM6/BLM interaction, we employed fluorescence polarization anisotropy analysis, NMR chemical shifts perturbation analys
