Histone amplification
Webb26 okt. 2006 · Proper histone levels are critical for transcription, chromosome segregation, and other chromatin-mediated processes(1-7). In Saccharomyces cerevisiae, the histones H2A and H2B are encoded by two gene pairs, named HTA1-HTB1 and HTA2-HTB2 (ref. 8). Previous studies have demonstrated that when HTA2-HT … Webb1 apr. 2010 · Our previous work showed that one mechanism by which S. cerevisiae maintains proper histone levels is by amplification of a histone H2A-H2B locus, HTA2-HTB2 (Libuda and Winston 2006). This amplification was shown to occur in response to reduced H2A-H2B levels caused by deletion of the other H2A-H2B locus, HTA1-HTB1.
