 Introduction

Protein palmitoylation is a post-translational modification that plays a crucial role in protein trafficking and function. It involves the addition of a lipid molecule, palmitate, to specific cysteine residues of proteins. Palmitoylation is unique in that it is reversible and dynamically regulated by specific extracellular signals. This literature review aims to combine and compare the work and application of the provided papers on protein palmitoylation and to discuss the progress made in this field in recent years.

 Literature Review

The literature review includes six papers that discuss protein palmitoylation from different angles. Dunphy and Linder[1] discuss the signaling functions of protein palmitoylation, while Ji[2] focuses on mass spectrometry analysis of protein/peptide S-palmitoylation. Chamberlain[3] reviews protein palmitoylation and subcellular trafficking, and Smotrys and Linder[4] discuss the regulation and function of palmitoylation of intracellular signaling proteins. Roth et al. [5] present a global analysis of protein palmitoylation in yeast, and Davda[1] provides a functional analysis of protein S-palmitoylation enzymes.

The papers provide a comprehensive understanding of the crucial role of palmitoylation in biological systems, the discovery of the DHHC protein family that catalyzes protein palmitoylation, and the molecular mechanisms of protein palmitoylation. The reversible nature of protein palmitoylation enables proteins to shuttle between intracellular compartments upon extracellular signals. The papers also discuss the pharmacological tools, animal models, and genetic approaches used to study protein palmitoylation.

 Progress Made

In recent years, there have been significant advances in the experimental tools used to study protein palmitoylation. Palsuledesai and Distefano[2] discuss the enzymes, therapeutics, and biotechnology applications of protein prenylation, while Linder and Deschenes[2] present model organisms that lead the way to protein palmitoyltransferases. Fukata et al. [2] identify PSD-95 palmitoylating enzymes, and Lobo et al. [2] identify a Ras palmitoyltransferase in Saccharomyces cerevisiae. Kong et al. [2] show that dynamic palmitoylation links cytosol-membrane shuttling of acyl-protein thioesterase-1 and acyl-protein thioesterase-2 with that of proto-oncogene H-Ras product.

Palsuledesai and Distefano[2] also discuss the enzymes, therapeutics, and biotechnology applications of protein prenylation. They highlight the potential of protein prenylation as a therapeutic target for cancer, infectious diseases, and neurodegenerative disorders. Linder and Deschenes[2] present model organisms that lead the way to protein palmitoyltransferases. They discuss the use of yeast, Drosophila, and mice to identify and characterize palmitoyltransferases and their substrates. Fukata et al. [2] identify PSD-95 palmitoylating enzymes, which play a crucial role in synaptic plasticity and learning and memory. Lobo et al. [2] identify a Ras palmitoyltransferase in Saccharomyces cerevisiae, which is involved in the regulation of cell growth and differentiation. Kong et al. [2] show that dynamic palmitoylation links cytosol-membrane shuttling of acyl-protein thioesterase-1 and acyl-protein thioesterase-2 with that of proto-oncogene H-Ras product, which is involved in the regulation of cell proliferation and differentiation.

 Conclusion

In conclusion, protein palmitoylation is a post-translational modification that plays a crucial role in protein trafficking and function. The literature review shows that significant progress has been made in recent years in the study of protein palmitoylation, including the discovery of palmitoyl-acyl transferases, the identification of specific enzymes for palmitoylated proteins, and the use of animal models to study protein palmitoylation. 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.
