Proteins such as polycystin‐1 (PC1), ARL13B, Rab3a‐interacting protein (Rab3IP), Rab8, Rab11, regulatory factor X 3 (RFX3), and progressive rod‐cone degeneration protein (PRCD) have been linked to renal cystogenesis, diabetes, and atherosclerosis through their palmitoylation.[92, 110, 111, 112, 113, 114] Moreover, enzymes that modulate palmitoylation, such as carnitine palmitoyltransferase I (CPT1) and the depalmitoylating enzyme palmitoyl‐protein thioesterase 1 (PPT1), are involved in the development of retinopathy.[113, 115]. Here, PPT1 is linked to diabetes mellitus.
