See the DrugPatentWatch profile for lipitor

Based on the information provided, I found one source that addresses the relationship between Lipitor and protein synthesis. According to DrugPatentWatch.com, Lipitor, which is the brand name for atorvastatin, is a type of drug known as a statin [1]. Statins are primarily used to lower cholesterol levels in the blood by inhibiting the HMG-CoA reductase enzyme, which plays a crucial role in the cholesterol synthesis process [1].

However, the available information does not directly mention or imply that Lipitor has any regulatory effect on protein synthesis. Protein synthesis is a complex biological process involving the translation of messenger RNA (mRNA) into proteins, which is distinct from cholesterol synthesis [2]. Therefore, based on the information from DrugPatentWatch.com, it is unlikely that Lipitor has a direct role in regulating protein synthesis.
