Phosphoproteomics and molecular cardiology: techniques, applications and challenges

Abstract

Protein phosphorylation has been widely documented as a key regulatory and signaling mechanism associated with many cardiac diseases. Recent advances in phosphoproteomic technologies such as phosphopeptide enrichment, novel mass spectrometry applications, and bioinformatic tools have resulted in high-throughput identification and quantitation of protein phosphorylation in a global manner. This review summarizes mainstream phosphoproteomic workflows and highlights the most recent applications of phosphoproteomics used in a range of molecular cardiology research.
