N-terminal formylation-dependent protein interactions in human cells

ABSTRACT: N-terminal formylation of methionine is a unique protein modification found in prokaryotes, as well as in the mitochondria, chloroplasts, and even the cytosol of eukaryotic cells. Recent studies have revealed that human cells are capable of producing cytosolic proteins bearing N-terminal formylmethionine. This project aims to investigate N-terminal formylation-dependent interaction changes of the human tumor protein TPD54. Specifically, HeLa cells were transfected with TPD54-BirA*, along with either E. coli formyltransferase (EcFMT) or its catalytically inactive R43L mutant, to manipulate the formylation status.

Chromosome localization of cohesin oligomers in mid-M arrested yeast cells

Project description:We report the genomic localization of cohesin oligomers in nocodazole arrested yeast cells. Two alleles of SMC3 were expressed in yeast cells, one fused to BirA enzyme and the other tagged with AviTag. Cohesin oligomers were biotinylated and ChIP with streptavidin beads. As control experiments, cohesin localization on chromosome was determined in strains expresses freely diffusable BirA enzyme, where all Smc3 proteins were biotinylated; non-specific ChIP were determined in strains with no BirA.

Multiple cellular compartments engagement in Nicotiana benthamiana-peanut stunt virus-satRNA interactions revealed by systems biology approach

Project description:Virus infection is a process resulting in numerous molecular, cellular, and physiological changes, a wide range of which can be analyzed due to development of many high-throughput techniques. Plant RNA viruses are known to replicate in the cytoplasm; however, the roles of chloroplasts and other cellular structures in the viral replication cycle and in plant antiviral defense have been recently emphasized. Therefore, the aim of this study was to analyze the small RNAs, transcripts, proteins, and phosphoproteins affected during peanut stunt virus strain P (PSV-P)–Nicotiana benthamiana interactions with or without satellite RNA (satRNA) in the context of their cellular localization or functional connections with particular cellular compartments to elucidate the compartments most affected during pathogenesis at the early stages of infection. Moreover, the processes associated with particular cell compartments were determined. The ‘omic’ results were subjected to comparative data analyses. Transcriptomic and small RNA (sRNA)–seq data were obtained to provide new insights into PSV-P–satRNA–plant interactions, whereas previously obtained proteomic and phosphoproteomic data were used to broaden the analysis to terms associated with cellular compartments affected by virus infection. Based on the collected results, infection with PSV-P contributed to changes in the abundance of transcripts and proteins associated with various cellular compartments, including ribosomes, chloroplasts, mitochondria, the nucleus and the cytosol, and the most affected processes were photosynthesis, translation, transcription, and mRNA splicing. Furthermore, sRNA-seq and phosphoproteomic analyses indicated that kinase regulation resulted in decreases in phosphorylation levels. The kinases were associated with the membrane, cytoplasm, and nucleus components.

Effects of CEBPA isoform expression on NB4 cells

Project description:Here we investigated the effects of CEBPA transcription factor expression on myeloid NB4 cells. The sequence of rat CEBPA was C-terminally fused to a promiscuous biotin ligase tag (BirA*) and NB4 cell lines were engineered to express the fusion protein under the control of a doxycycline inducible promoter. Three different NB4 cell lines were investigated that expressed (i) BirA* tag alone (ii) full length CEBPA isoform (P42) fused to BirA* (iii) truncated CEBPA isoform (P30) fused to BirA*. Cells were seeded in media supplemented with or without doxycycline.

Expression of a dominant‐negative AtNEET‐H89C protein disrupts iron–sulfur metabolism and iron homeostasis in Arabidopsis

Project description:Iron–sulfur (Fe–S) clusters play an essential role in plants as protein cofactors mediating diverse electron transfer reactions. Because they can react with oxygen to form reactive oxygen species (ROS) and inflict cellular damage, the biogenesis of Fe–S clusters is highly regulated. A recently discovered group of 2Fe–2S proteins, termed NEET proteins, was proposed to coordinate Fe–S, Fe and ROS homeostasis in mammalian cells. Here we report that disrupting the function of AtNEET, the sole member of the NEET protein family in Arabidopsis thaliana, triggers leaf‐associated Fe–S‐ and Fe‐deficiency responses, elevated Fe content in chloroplasts (1.2–1.5‐fold), chlorosis, structural damage to chloroplasts and a high seedling mortality rate. Our findings suggest that disrupting AtNEET function disrupts the transfer of 2Fe–2S clusters from the chloroplastic 2Fe–2S biogenesis pathway to different cytosolic and chloroplastic Fe–S proteins, as well as to the cytosolic Fe–S biogenesis system, and that uncoupling this process triggers leaf‐associated Fe–S‐ and Fe‐deficiency responses that result in Fe over‐accumulation in chloroplasts and enhanced ROS accumulation. We further show that AtNEET transfers its 2Fe–2S clusters to DRE2, a key protein of the cytosolic Fe–S biogenesis system, and propose that the availability of 2Fe–2S clusters in the chloroplast and cytosol is linked to Fe homeostasis in plants.

N-terminal acetylation shields proteins from degradation and promotes age-dependent motility and longevity

Project description:Most eukaryotic proteins are N-terminally acetylated, but the functional impact on a global scale has remained obscure. Using genome-wide CRISPR knockout screens in human cells, we reveal a strong genetic dependency between a major N-terminal acetyltransferase and specific ubiquitin ligases. Biochemical analyses uncover that both the ubiquitin ligase complex UBR4-KCMF1 and the acetyltransferase NatC recognize proteins bearing an unacetylated N-terminal methionine followed by a hydrophobic residue. NatC KO-induced protein degradation and phenotypes are reversed by UBR knockdown, demonstrating the central cellular role of this interplay. We reveal that loss of Drosophila NatC is associated with male sterility, reduced longevity, and age-dependent loss of motility due to developmental muscle defects. Remarkably, muscle-specific overexpression of UbcE2M, one of the proteins targeted for NatC KO mediated degradation, suppresses defects of NatC deletion. In conclusion, NatC-mediated N-terminal acetylation acts as a protective mechanism against protein degradation, which is relevant for increased longevity and motility.
