Chromatin Enzyme Logic: Writer-Reader-Eraser Specificity and Cross-talk

Chromatin epigenomics has revealed a dynamic landscape of biochemical modifications that regulate genome function, cellular memory, and developmental potential. At the center of this landscape, chromatin-modifying enzymes - writers, readers, and erasers - collaborate and compete to deposit, remove, and recognize specific epigenetic marks. However, the principles governing the specificity and integration of actions among these enzymes, often referred to as “chromatin enzyme logic,” are only beginning to be understood. Current research highlights complex networks of cross-talk, feedback, and combinatorial regulation that bridge chromatin state to cellular identity and plasticity, yet substantial gaps remain in elucidating how these enzyme systems are coordinated in real time and across different biological contexts.This Research Topic aims to systematically investigate how the specificity and interactions among chromatin writers, readers, and erasers orchestrate epigenomic states and transitions in development, health, and disease. Key objectives include defining the molecular mechanisms that underlie substrate selection, deciphering the multi-dimensional networks of enzyme cross-talk, and understanding how these interactions influence chromatin architecture and gene regulation. We also seek to address how environmental, metabolic, and developmental signals modulate the activity and cooperation of these chromatin-modifying complexes. By integrating biochemical, structural, genomic, and computational insights, the goal is to establish a cohesive framework for understanding chromatin enzyme logic at the systems level.This Research Topic is limited to studies that advance our mechanistic, functional, or computational understanding of chromatin-modifying enzymes - writers, readers, and erasers -and their contributions to epigenetic regulation in eukaryotic systems. We especially welcome submissions employing interdisciplinary epigenomic tools, developmental and disease models, and innovative approaches in plant and animal systems. Themes of interest include, but are not limited to:Enzyme specificity and combinatorial regulation in establishing and removing histone and non-histone modificationsStructural biology and mechanistic studies of chromatin-modifying complexesCross-talk between chromatin marks and integrating epigenetic signalsRoles of writer–reader-eraser interactions in cellular differentiation, reprogramming, and memoryChromatin enzyme dysregulation in cancer, neurodevelopmental, metabolic, and inflammatory diseasesEpigenetic modulation by metabolic and environmental factorsApplication of single-cell, spatial, or multi-omics tools to dissect chromatin enzyme logicTo further knowledge in chromatin enzyme biology and its impact on cell fate and health, we welcome original research articles, reviews, methods, and perspectives addressing these foundational and emerging themes.
