Abstract
Recent advancements in Genetic Code Expansion (GCE) have significantly enhanced our understanding of post-translational modifications (PTMs), which are critical for protein regulation. GCE facilitates the precise incorporation of unnatural amino acids (UAAs) at specific sites within proteins of interest (POIs), making it a powerful tool for modulating PTMs in vivo. This review summarizes the various UAAs utilized to directly incorporate PTMs into proteins through GCE, with a focus on their applications in both histone and non-histone PTMs research. We also discuss the challenges associated with incorporating certain PTMs into target proteins via GCE and provide an overview of the latest strategies developed to overcome these hurdles.
