摘要
Site-directed mutagenesis (SDM) is a technique in molecular biology and protein engineering that is widely used to determine the significance of specific residues involved in post-translational modifications (PTMs), protein structure, function, and stability. Here, we describe a simple and cost-effective polymerase chain reaction (PCR)-based SDM method. This method can be used to introduce point mutation, short addition, or deletions in protein sequences. Using polycomb repressive complex-2 (PRC2)-associated protein JARID2 as an example, we demonstrate how SDM can be used to study structural and consequently functional changes in a protein.
