General description
Histone MacroH2A (mH2A) is a variant histone also known as H2AFY. mH2A is enriched in chromatin of the female inactive X chromosome and in highly methylated CpG loci. This histone variant is known to repress RNA polymerase II-driven transcription at the level of transcriptional initiation. In contrast to most histone variants containing only subtle changes, mH2A contains a large non-histone domain (the macro domain) on its C-terminus, resulting in a histone approximately three times the size of conventional H2A. There are 3 isoforms of mH2A, two of which (mH2A1.1, mH2A1.2 ) are formed by alternative splicing and another (mH2A2) from a separate gene. There are two phosphorylation sites within the basic hinge region of mH2A: Thr128 and Ser137. Phospho-Ser137 is enriched in mitosis, implicating mH2A in the regulation of posttranslational modifications throughout the cell cycle.

For over 130 years, invasive pneumococcal disease has been associated with the presence of extracellular planktonic pneumococci, i.e. diplococci or short chains in affected tissues. Herein, we show that Streptococcus pneumoniae that invade the myocardium instead replicate within cellular vesicles

Heterochromatin formation plays a pivotal role in regulating chromatin organization and influences nuclear architecture and genome stability and expression. Amongst the locations where heterochromatin is found, the pericentric regions have the capability to attract the histone variant macroH2A1. However, the
macroH2A2 antagonizes epigenetic programs of stemness in glioblastoma.
