Abstract:

Palmitoyl protein thioesterase 1(PPT1) is a lysosomal enzyme that catalyzes the protein depalmitoylation. It is considered to play a crucial role in regulating lysosomes, mitochondria and lipid metabolism. PPT1 has been reported to play an important role in the occurrence and progression of diseases, such as neurological diseases and cancers. However, the regulatory mechanisms remain unknown. In this review, we summarize the progress of PPT1 function and mechanisms in neurological disorders and cancers, which will provide as reference and guidance for exploring the regulatory mechanisms of PPT1 and developing new drugs for treating related diseases in the future.

Key words: Palmitoyl protein thioesterase 1, depalmitoylation, lysosome, disease
