• How to Detect Histone Propionylation Modifications?
Post-translational modifications (PTMs) of histones represent a crucial level of epigenetic regulation. Among them, propionylation, an emerging type of acylation, has received widespread attention in recent years. Propionylation modulates chromatin structure and transcriptional activity by altering the charge and spatial conformation of lysine residues and plays a key role in processes such as metabolic regulation, tumorigenesis, and inflammatory responses. With advances in high-resolution mass spectr......

• What Does Histone Khib Mean in Epigenetic Regulation?
In the past decade, the development of high-resolution mass spectrometry has significantly advanced research on protein post-translational modifications (PTMs). Beyond classical modifications such as acetylation and methylation, a new class of lysine acylations has attracted increasing attention. Among these, lysine β-hydroxyisobutyrylation (Khib) has emerged as a prominent focus in epigenetic research. What Is Histone Khib Modification? Khib is a novel acylation occurring on lysine residues and was ......
