New Types of Post-Translational Modification of Proteins in Cardiovascular Diseases

Abstract

Post-translational modifications (PTMs), which are covalent alterations of proteins after their synthesis, are critical for their proper function and the maintenance of cellular physiology. The significance of PTMs in the context of cardiovascular diseases (CVDs) has been increasingly recognized due to their potential to influence protein stability, activity, and localization, thereby affecting the progression of CVDs. The identification and understanding of PTMs in CVDs at the molecular level are vital for the discovery of new biomarkers and new targets for clinical interventions. This article provides a comprehensive overview of the role and mechanisms of new types of PTMs, such as acetylation, crotonylation, succinylation, S-nitrosylation, malonylation, S-palmitonylation, β-hydroxybutyrylation and lactylation, in CVDs, highlighting their importance in advancing diagnostic and therapeutic approaches for CVDs.
