Background
Lysine butyrylation is a newly identified reversible modification controlling protein activity. With integrated proteomic approaches and biochemistry analysis, lysine butyrylation has been well demonstrated in both prokaryotes and eukaryotes in wide ranges of proteins including histones and non-histone substrates. Lysine butyrylation may play a vital role in epigenetic modulation by impacting chromatin dynamics and lasticity, DNA transcriptional regulation and tumorigenesis, etc.
