Blog InsertThere have been many recent advances in methodologies to detect the only reversible lipidation reaction of proteins, S-palmitoylation. This fatty acyl post translational modification has gained great interest in the research community as it is increasingly recognised as important in both health and disease. In this article I will briefly examine the development of the acyl exchange methodologies used by researchers to measure S-palmitoylation. I will focus in particular on the recently published Acyl PEG Exchange (APE) /Acyl PEGyl Gel Shift (APEGS) assay, paying particular attention to the advantages it offers scientists interested in exploring palmitoylation.
