About

Qishun Zhou is a structural biologist whose research centers on protein post-translational modifications, with a particular focus on arginine methylation and its role in cellular regulation. Their major contribution lies in developing innovative nuclear magnetic resonance (NMR) spectroscopy methods to probe the "arginine methylome"—the complete set of arginine-methylated proteins in a cell. Zhou’s landmark 2021 protocol, cited over 10 times, provides an easily implementable approach for quantifying arginine methylation states, enabling researchers to dissect how this modification alters protein physicochemical properties and modulates interactions with other proteins or nucleic acids. This work has advanced our understanding of how arginine methylation governs key biological processes, from gene expression to signal transduction. By bridging NMR technology and epigenetics, Zhou has established a powerful tool for the field, with their protocol serving as a foundational resource for labs studying methylation-dependent regulation. Their research continues to illuminate the molecular mechanisms underlying arginine methylation, offering potential insights into diseases where these pathways are disrupted.
