Protein S-palmitoylation is a post-translational lipid modification that regulates the stability and cellular distribution of numerous cancer-related proteins. A family of 23 palmitoyl transferases, called zinc finger Asp-His-His-Cys-type (ZDHHC), mediates this lipid modification. However, the potential role of palmitoyl transferases in tumor progression and immunotherapy in pancreatic adenocarcinoma (PAAD) remains unexplored.
