Abstract
Protein mislocalization is a key initial step in neurodegeneration, regardless of etiology, and has been linked to changes in the dynamic addition of saturated fatty acids to proteins, a process known as S-acylation. With the advent of new techniques to study S-acylation and the recent discovery of new enzymes that facilitate protein deacylation, novel small molecules are emerging as potential new therapeutic treatments. Huntington disease (HD) is a devastating, fatal neurodegenerative disease characterized by motor, cognitive, and psychiatric deficits caused by a CAG repeat expansion in the HTT gene. The protein that is mutated in HD, huntingtin, is less S-acylated which is associated with mutant HTT aggregation and cytotoxicity. Recent exciting findings indicate that restoring S-acylation in HD models using small molecule inhibitors of the deacylation enzymes is protective. Herein, we set out to describe the known roles of S-acylation in HD and how it can be targeted for therapeutic design.
