the application and progress of Protein palmitoylation

 Introduction

Protein palmitoylation is a post-translational modification that involves the covalent attachment of palmitic acid to cysteine residues of proteins. This modification plays a crucial role in protein trafficking, stability, and activity. This literature review aims to discuss the application and progress of protein palmitoylation in the past few years.

 Application of Protein Palmitoylation

Protein palmitoylation plays diverse roles in regulating the trafficking, stability, and activity of cellular proteins[1]. The reversible nature of protein palmitoylation enables proteins to shuttle between intracellular compartments upon extracellular signals, making it a crucial mechanism for maintaining homeostasis and responding to extracellular signals. Protein palmitoylation has been implicated in various cellular processes, including cellular differentiation[1], synaptic plasticity, and learning and memory[2]. The pharmacological tools, animal models, and genetic approaches used to study protein palmitoylation have potential therapeutic applications for cancer, infectious diseases, and neurodegenerative disorders[3].

 Progress of Protein Palmitoylation

In recent years, there have been significant advances in the experimental tools used to study protein palmitoylation. The use of mass spectrometry has enabled the identification of palmitoylated proteins and the specific sites of palmitoylation[4]. The development of click chemistry has facilitated the study of protein palmitoylation in living cells and the identification of new palmitoylated proteins[2]. The use of animal models has enabled the study of the physiological and pathological roles of protein palmitoylation[3].

Recent studies have shown that protein palmitoylation plays a crucial role in cellular differentiation[1]. The reversible nature of protein palmitoylation enables proteins to shuttle between intracellular compartments upon extracellular signals, making it a crucial mechanism for maintaining homeostasis and responding to extracellular signals. The pharmacological tools, animal models, and genetic approaches used to study protein palmitoylation have potential therapeutic applications for cancer, infectious diseases, and neurodegenerative disorders.
