Proteins can be radiolabeled either during synthesis, typically using 35S-cysteine/methionine (35S-Cys/Met), or after synthesis, by adding a radiolabeled posttranslational modification. Here we describe how protein S-palmitoylation, and its dynamics, can be monitored by 3H-palmitate labeling and how the importance of S-palmitoylation in protein biogenesis and turnover can be investigated using 35S-Cys/Met pulse–chase metabolic labeling. Proteins frequently have multiple palmitoylation sites. The importance thereof on the design and interpretation of metabolic labeling experiments is discussed.
