MacroH2A is a histone H2A variant that is typically found in heterochromatic regions of the genome. A positively charged linker that connects the histone-fold with the macro-domain was suggested to have DNA-binding properties, and has been shown to promote oligomerization of chromatin fibers. Here we examine the influence of this basic linker on DNA of mononucleosomes. We find that the macro-linker reduces accessibility to extranucleosomal DNA, and appears to increase compaction of the nucleosom ...[more]
