摘要
Post-translational modifications(PTM)are covalent modifications of proteins or peptides caused by proteolytic cleavage or the attachment of moieties to one or more amino acids.PTMs play essential roles in biological function and regulation and have been linked with several diseases.Modifications of protein acylation(Kac),a type of PTM,are known to induce epigenetic regulatory processes that promote various diseases.Thus,an increasing number of studies focusing on acylation modifications are being undertaken.Butyrylation(Kbu)is a new acylation process found in animals and plants.Kbu has been recently linked to the onset and progression of several diseases,such as cancer,cardiovascular diseases,diabetes,and vascular dementia.Moreover,the mode of action of certain drugs used in the treatment of lymphoma and colon cancer is based on the regulation of butyrylation levels,suggesting that butyrylation may play a therapeutic role in these diseases.In addition,butyrylation is also commonly involved in rice gene expression and thus plays an important role in the growth,development,and metabolism of rice.The tools and analytical methods that could be utilized for the prediction and detection of lysine butyrylation have also been investigated.This study reviews the potential role of histone Kbu,as well as the mechanisms underlying this process.It also summarizes various enzymes and analytical methods associated with Kbu,with the goal of providing new insights into the role of Kbu in gene regulation and diseases.
