Histone acetylation and deacetylation are the processes by which the lysine residues within the N-terminal tail protruding from the histone core of the nucleosome are acetylated and deacetylated as part of gene regulation. Histone acetylation and deacetylation are essential parts of gene … Visa mer Nucleosomes are portions of double-stranded DNA (dsDNA) that are wrapped around protein complexes called histone cores. These histone cores are composed of 8 subunits, two each of H2A, H2B, H3 and H4 histones. … Visa mer Transcription regulation The discovery of histone acetylation causing changes in transcription activity can be traced back to the work of Vicent Allfrey and … Visa mer • Histone acetyltransferase • Histone deacetylase • Histone methylation • Acetylation • Phosphorylation Visa mer Histone acetyltransferase (HATs) Histone Acetyltransferases, also known as HATs, are a family of enzymes that acetylate the histone tails of the nucleosome.
