Schizosaccharomyces pombe Ppr10 and Mpa1 together mediate mitochondrial translational initiation.

Luo Ying Y Wang Yirong Y Huang Ying Y

The Journal of biological chemistry 20210610 1

Pentatricopeptide repeat (PPR) proteins are a large family of proteins that act primarily at different posttranscriptional steps of organellar gene expression. We have previously found that the Schizosaccharomyces pombe PPR protein mpal10 interacts with mitochondrial translational activator Mpa1, and both are essential for mitochondrial protein synthesis. However, it is unclear how these two proteins function in mitochondrial protein synthesis in S. pombe. In this study, we further investigated ...[more]

Transcription start site profiling of a Streptococcus pyogenes emm1 strain

Project description:The human pathogen Streptococcus pyogenes, or group A streptococcus, is responsible for mild infections to life-threatening diseases. To determine the primary transcriptome of the emm1 strain S119, we have performed a differential RNA-Seq experiment based on selective Tobacco Acid Pyrophosphatase (TAP) treatment and 5' adapter ligation to differentiate primary transcripts (5' tri-phosphate) and processed RNAs (5' mono-phosphate). The libraries were performed on a mixture of RNAs prepared from bacteria cultured to late exponential phase in a rich growth culture medium supplemented or not with 15 mM of MgCl2

ChIP-nexus analysis of fission yeast transcription factors Cbf11, Cbf11DBM, Cbf12, Cbf12DBM, Mga2 and Fkh2

Project description:Genome-wide identification of transcription factor (TF) binding sites in the genome of the fission yeast Schizosaccharomyces pombe. The ChIP-nexus method was used. TFs included were: Cbf11-TAP and Cbf12-TAP (and their DBM mutants with impaired DNA binding), TAP-Mga2, and Fkh2-TAP (as an irrelevant control TF). IPs from an untagged WT strain were also analyzed. Cbf11-related IPs were performed from exponential cultures, while Cbf12-related IPs were performed from stationary cultures. YES complex medium was used for all cultivations.

Transcription profiling by array of human MCF-7 breast cell clones expressing ER-beta tagged with TAP-tag at the C-terminal or N-terminal

Project description:MCF-7 TET Off cells (MCF-7 wt) were used to produce stable clones expressing ER-beta tagged with TAP-tag respectively at the C-term and at the N-term (C-TAP-ER-beta and N-TAP-ER-beta) or expressing ER-alpha tagged (C-TAP-ER-alpha) as previously described.Cells were cultured in standard growth conditions, then were lysed and RNA was extracted using TRIzol method.Total RNA were fluorescently labelled, amplified and hybridized in triplicate (MCF7-TAP and C-TAP-ER-alpha) and in duplicate (C-TAP-ER-beta_A, C-TAP-ER-beta_B, N-TAP-ER-beta) for 18 hours on Illumina v2 MicroRNA Expression BeadChips and after scanning, analysis was performed with GenomeStudio v.2010.1 software, for quality control and miRNA expression analysis.

Nuclear nucleolin interactome analysis

Project description:Nucleolin (NCL) is a major component of the cell nucleolus, which has the ability to rapidly shuttle to several other cell’s compartments. NCL has been shown to play important roles in a variety of essential functions among which ribosome biogenesis, gene expression and cell growth. However, the precise mechanisms underlying NCL functions are still unclear. Our study aimed to provide new information on NCL functions via the identification of its nuclear interacting partners. Using an interactomics approach, we identified 140 binding partners of NCL, among which, a 100 of them, were specifically found associated to NCL independently of the presence of RNA.

Microarray analysis of TAP::ALG-1 associated RNAs isolated from synchronized 'wild-type' animals and 'mir-58' mutants

Project description:To discover new miRNA targets, we generated a C. elegans transgenic line expressing a functional N-terminally Tandem Affinity Purification (TAP) tagged ALG-1 protein (C. elegans strain WS4303). We crossed the TAP::ALG-1 transgene into the mir-58(n4640) mutant background to generate the strain WS5041. For simplicity, we will hereafter term the TAP::ALG-1 transgenic animals as wild typeand the transgenic WS5041 animals as mir-58. We compared the mRNA population that coimmunopurified with TAP::ALG-1 from synchronized L4 stage wild-type animals with that from synchronized L4 stage mir-58 mutant animals by one-color Affymetrix gene arrays. miR-58 target mRNAs should be specifically underrepresented in the latter samples. Strains WS4303 (wt) and WS5041 (mir-58) were used for TAP::ALG-1 IPs. All experiments were conducted in three independent replicates. For each replicate, WS4303 and WS5041 were grown in parallel. 150 ng of TAP::ALG-1 associated RNA isolated from synchronized late L4 animals were sent to the GeneCore facilty in Heidelberg, Germany (http://www.genecore.embl.de/index.cfm), and the microarray data were generated according to their standard protocol (Weinmann et al. 2009).

Endogenous brain ARC complexes

Project description:Arc is an activity regulated neuronal protein yet little is known about its protein interactions, assembly into multiprotein complexes, role in human disease and cognition. We applied an integrated proteomic and genetic strategy using targeted tagging of a Tandem Affinity Purification (TAP) tag and Venus fluorescent protein into the endogenous Arc gene in mice, biochemical and proteomic characterization of native complexes in wild type and knockout mice, and human genetic analyses of disease and intelligence. TAP tagging enabled efficient purification of complexes and identification of many novel Arcinteracting proteins, of which PSD95 was the most abundant. PSD95 was essential for Arc assembly into 1.5 MDa complexes and activity-dependent recruitment to excitatory synapses. Integrating human genetic data with proteomic data showed postsynaptic Arc- PSD95 complexes are enriched in schizophrenia, intellectual disability, autism and epilepsy mutations and normal variants in intelligence. Arc-PSD95 postsynaptic complexes are a molecular substrate for the convergence of normal and pathological genetic variants impacting on human cognitive function.
