The continuing identification of new histone post-translational modifications and ongoing discovery of their roles in nuclear processes has increased the demand for quick, efficient, and precise methods for their analysis. In the budding yeast Saccharomyces cerevisiae, a variety of methods exist for the characterization of histone modifications on a global scale. However, a wide gap in preparation...
The use of the budding yeast Saccharomyces cerevisiae as a simple eukaryotic model system for the study of chromatin assembly and regulation has allowed rapid discovery of genes that influence this complex process. The functions of many of the proteins encoded by these genes have not yet been fully characterized. Here, we describe a high-throughput methodology that can be used to illuminate gene function...
Post-translational modifications of histones have been correlated with virtually all chromatin-templated processes, including gene expression regulation, DNA replication, mitosis and meiosis, and DNA repair. In order to better understand the mechanistic basis by which histone modifications participate in the control of cellular processes, it is essential to identify and characterize downstream effector...
Post-translational modifications to histone proteins regulate the packaging of genomic DNA into chromatin, gene activity and other functions of the genome. They are understood to play key roles in embryonic development and disease pathogenesis. Recent advances in technology have made it possible to analyze chromatin structure genome-wide in mammalian cells. Global patterns of histone modifications...
Chromatin modifying and remodeling enzymes play critical roles in many aspects of chromosome biology including transcription, replication, recombination, and repair. Our laboratory recently identified and characterized two multisubunit human chromatin remodeling enzymes designated the INO80 and SRCAP complexes. Mechanistic studies revealed that the human INO80 complex catalyzes nucleosome sliding...
