Cell survival under severe thermal stress requires the activity of the ClpB (Hsp104) AAA+ chaperone that solubilizes and reactivates aggregated proteins in concert with the DnaK (Hsp70) chaperone system. How protein disaggregation is achieved and whether survival is solely dependent on ClpB-mediated elimination of aggregates or also on reactivation of(More)
Nucleosomes are decorated with numerous post-translational modifications capable of influencing many DNA processes. Here we describe a new class of histone modification, methylation of glutamine, occurring on yeast histone H2A at position 105 (Q105) and human H2A at Q104. We identify Nop1 as the methyltransferase in yeast and demonstrate that fibrillarin is(More)
Ageing has been associated with structural changes in chromatin. At the molecular level, multiple histone modifications with established epigenetic mechanisms have been connected to the regulation of lifespan. Here, we review the changes in histone modification profiles during ageing and their possible functional contribution to ageing and lifespan(More)
