Histone Modification Studies EpigenTek

The tight wrapping of DNA around histones is to a large degree a result of electrostatic attraction between the positively charged histones and negatively charged phosphate backbone of DNA. Histones may be chemically modified through the action of enzymes to regulate gene transcription.

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.
