WebbHistone H3 is one of the DNA-binding proteins found in the chromatin of all eukaryotic cells. H3 along with four core histone proteins binds to DNA forming the structure of the nucleosome. Histones play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. Webb3 mars 2024 · H3K27 is a specific histone protein (H3) that is acetylated at lysine 27 (H3K27Ac), a marker of transcriptional activity. Thus, the inhibition of H3K27 acetylation may orchestrate the expression of IL-9 in kidney diseases.
WebbAcetylation of histone H3 at Lys27 is associated with transcriptional activation. Histone H3K27 can also be mono-, di-or trimethylated by different histone methyltransferases, such as EZH2 or NSD3. While histone methylation can be associated with transcriptional activation or repression, ...
