Histone Acetyltransferase 1 Links Metabolism and Transcription to Cell-Cycle Progression.

abstract：:The Mre11/Rad50/Nbs1 complex initiates double-strand break repair by homologous recombination (HR). Loss of Mre11 or its nuclease activity in mouse cells is known to cause genome aberrations and cellular senescence, although the molecular basis for this phenotype is not clear. To identify the origin of these defects, ...
