Cellular differentiation from stem cells to fully functional mature cells is a multi step process executed by complex transcription programs. Once differentiated, cells must faithfully maintain their identity through cellular memory mechanisms. The utilisation of genetic information stored in linear DNA sequence occurs within the three dimensional context of chromatin, chromosomes and the nucleus, ...

The histone variant macroH2A1 (mH2A1) is associated with gene repression but the molecular mechanisms by which it exerts its function are largely unknown. mH2A is recruited to the IL-8 promoter by ATF-2 where it functions as a transcriptional repressor. Interestingly, macroH2A1 has been shown to bind O-acetyl-ADP-ribose (OAADPR).The functional consequences of this interaction are unknown. This pro ...
