Special Issue Information

Dear Colleagues,

The central dogma of molecular biology outlines the information flow from the nucleic acid sequences of genes in the genome to messenger RNAs (mRNAs) in the transcriptome and ultimately to the defined sequences of amino acids, which are the building blocks of all proteins in every living cell. Mutations in protein-coding genes can cause the production of proteins that differ from the wild-type sequences and that, in some cases, lead to defects in cells or cause disease. Two additional major routes generate changes in the protein sequence, even in the absence of mutations in the gene itself. One route involves the post-translational modification of proteins with a wide array of non-canonical amino acids, including acetylated, phosphorylated, or methylated amino acids that can have a dramatic impact on protein function. Indeed, there are many examples of hyper- or hypo-modified proteins associated with diverse human diseases. Another route to alter protein sequences involves mutations in transfer RNAs (tRNAs) or aminoacyl-tRNA synthetases that cause mistakes in protein synthesis or mistranslation of the genetic code. Mistranslation leads to the incorporation of the wrong amino acid at a codon or set of codons throughout the entire proteome. This Special Issue of Cells focuses on how protein modification and mistranslation alter the nature of proteins produced from otherwise wild-type genes. For this Special Issue, we welcome the submission of original research articles and reviews that highlight the impact of protein modification and errors in protein synthesis on normal cellular behaviour, protein homeostasis, and human disease.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cells is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Protein S-palmitoylation, a type of post-translational modification, refers to the reversible process of attachment of a fatty acyl chain—a 16-carbon palmitate acid—to the specific cysteine residues on target proteins. By adding the lipid chain to proteins, it increases the hydrophobicity of proteins and modulates protein stability, interaction with effector proteins, subcellular localization, and membrane trafficking. Palmitoylation is catalyzed by a group of zinc finger DHHC-containing proteins (ZDHHCs), whereas depalmitoylation is catalyzed by a family of acyl-protein thioesterases. Increasing numbers of oncoproteins and tumor suppressors have been identified to be palmitoylated, and palmitoylation is essential for their functions. Understanding how palmitoylation influences the function of individual proteins, the physiological roles of palmitoylation, and how dysregulated palmitoylation leads to pathological consequences are important drivers of current research in this research field. Further, due to the critical roles in modifying functions of oncoproteins and tumor suppressors, targeting palmitoylation has been used as a candidate therapeutic strategy for cancer treatment. Here, based on recent literatures, we discuss the progress of investigating roles of palmitoylation in regulating cancer progression, immune responses against cancer, and cancer stem cell properties.
