Complexome profiling on the lpa2 mutant

ABSTRACT: Chlamydomonas wild type CC 4533 and lpa2 mutant were grown in TAP medium at 25°C and ~30 µmol photons m^-2 s^-1 on a rotary shaker. Protein complexes of three wild type (wt) and three lpa2 (mut) samples were separated by BN-PAGE and cut into 36 slices. Subsequent mass spectrometry enables the analysis of protein complex migration patterns of wild type and mutant complexes.

While the composition and function of the major thylakoid membrane complexes are well understood, comparatively little is known about their biogenesis. The goal of this work was to shed more light on the role of auxiliary factors in the biogenesis of photosystem II (PSII). Here we have identified the homolog of LOW PSII ACCUMULATION 2 (LPA2) in Chlamydomonas. A Chlamydomonas reinhardtii lpa2 mutant grew slower in low light, was hypersensitive to high light, and exhibited aberrant structures in t ...[more]

Lysine acetylation of chloroplast proteins 2

Project description:In photosynthesis, light is absorbed by the thylakoid embedded light harvesting pigment protein complexes (LHCs) that surround the photosynthetic reaction centers, photosystem II (PSII) and photosystem I (PSI). The distribution of light energy between the photosystems is balanced through state transitions1,2, which refer to the phosphorylation-dependent association of the loosely bound (L) LHCII antenna trimer either to PSII or PSI 3,4. Apart from phosphorylation, other mechanisms regulating state transitions have not been reported this far. In this study we demonstrate that lysine (Lys) acetylation of chloroplast proteins is a prerequisite for state transitions in Arabidopsis thaliana. Knock-out mutants lacking a chloroplast acetyltransferase NSI (At1g32070; AtNSI, SNAT) show selective decreases in the Lys acetylation status of several photosynthetic proteins including PSI, PSII and LHCII subunits. Fluorescence measurements revealed that changes in the wavelength of illumination do not cause state transitions in the nsi mutants even though their LHCII phosphorylation status is not defected. Furthermore, biochemical analyses of thylakoid proteins and protein complexes showed that nsi plants are not able to accumulate the phosphorylation dependent PSI-LHCII megacomplex. Our results manifest that Lys acetylation by NSI has an integral role in the regulation of state transitions in Arabidopsis.

Identification of dGTP-interacting mitochondrial proteins by affinity purification and LC-ESI-MS/MS

Project description:Imbalanced mitochondrial dNTP pools are known players in the pathogenesis of multiple human diseases. However, we have shown that dGTP is largely overrepresented over the other dNTPs in mitochondria of mouse tissues and human cultured cells. Here, we have performed affinity purification studies and identified NDUFA10, an accessory subunit of respiratory complex I, as the protein binding most of the dGTP contained in mitochondria. This interaction provides a possible link between oxidative metabolism and regulation of dNTP availability and thus with DNA maintenance.

UHPLC-MS/MS analysis of S-nitrosylated proteins involved in autophagy in Triticum aestivum roots

Project description:In the present work, we analyzed the patterns of protein S-nitrosylation during the inductionof autophagy in сommon wheat (Triticum aestivum) roots. S-nitrosylated proteins were accumulated in plant tissues as a result of artificially induced autophagy, visualized usingWestern blot and identified by bottom-up proteomics methods. Further, the obtained data was analyzed by bioinformatics methods to predict possible S-nitrosylation sites and protein-protein interactions between S-nitrosylated proteins and possible targets. These resultscontribute to the development of the efficient protocols for identification and analysis of S-nitrosylated proteins in plants.

Identification of proteins associated with the human mitochondrial degradosome

Project description:The human mitochondrial degradosome is a complex of the ribonuclease PNPase (Q8TCS8, encoded by PNPT1 gene) and RNA helicase SUV3 (Q8IYB8, encoded by SUPV3L1 gene). The aim of the project was to identify proteins which co-purify with both subunits of the degradosome. To this end we used human 293 cells stably expressing hSuv3 or PNPase with a C-terminal TAP tag or TAP tag fused to a mitochondria targeting sequence (control bait) (cell lines are described in details in (PMID: 19864255). Mitochondria were isolated from the cells, lysed and the protein extracts were subjected to affinity chromatography. Co-purified proteins were identified by mass spectrometry and their amounts were quantified by a label-free approach (MaxQuant). These experiments are part of the project “Dedicated surveillance mechanism controls G-quadruplex forming non-coding RNAs in human mitochondria”.

Profiling of human spermatozoa glycoproteins by LC/MS/MS

Project description:N-linked glycoproteins are known to be important for spermatozoa development and gametes fusion. However, little is known about detailed information of these glycoproteins, particularly the glycosylation sites and its corresponding glycan structures in human spermatozoa. In present study, an in house software coupled with LC-MS/MS analysis of intact glycopeptides was employed to establish a large scale of site-specific N-glycoproteome map in human spermatozoa. The results mapped the large-scale N-glycoproteins in human spermatozoa and interpreted the precise glycan structures with the corresponding glycosites. These presented data laid the foundation for the exploration of biological function of glycosylation on human spermatozoa and glycan structure involved male infertility.

Proteomics Reveals Extracellular Matrix Injury in the Glomeruli and Tubulointerstitium of Kidney Allografts with Early Antibody-Mediated Rejection

Project description:Antibody-mediated rejection (AMR) accounts for >50% of kidney allograft losses. AMR is caused by donor-specific antibodies (DSA) against HLA and non-HLA antigens in the glomeruli and the tubulointerstitium, which together with high interferon gamma (IFNɣ) and tumor necrosis factor-alpha (TNFα), trigger graft injury. Unfortunately, the mechanisms governing cell-specific injury in AMR remain unclear. We studied 30 for-cause kidney biopsies with early AMR, acute cellular rejection or acute tubular necrosis (‘non-AMR’). We laser-captured microdissected glomeruli and tubulointerstitium and subjected them to unbiased proteome analysis. 120/2026 glomerular and 180/2399 tubulointerstitial proteins were significantly differentially expressed in AMR vs. non-AMR biopsies (p<0.05). Basement membrane and extracellular matrix (ECM) proteins were significantly decreased in both AMR compartments. We verified decreased glomerular and tubulointerstitial LAMC1 expression, and decreased glomerular NPHS1 and PTPRO expression in AMR. Cathepsin-V (CTSV) was predicted to cleave ECM-proteins in the AMR glomeruli, and CTSL, CTSS and LGMN in the tubulointerstitium. We identified galectin-1, an immunomodulatory protein upregulated in AMR glomeruli and linked to the ECM. Anti-HLA class-I antibodies significantly increased CTSV expression, and galectin-1 expression and secretion, in human glomerular endothelial cells. We also studied glutathione S-transferase omega-1 (GSTO1), an ECM-modifying enzyme, increased in the AMR tubulointerstitium. GSTO1 expression was significantly increased in TNFα-treated proximal tubular epithelial cells. IFNɣ and TNFα significantly increased CTSS and LGMN expression in these cells. Basement membranes are often remodeled in chronic AMR, and we demonstrated that this remodeling begins early in glomeruli and tubulointerstitium. Targeting ECM-remodeling in AMR may represent a new therapeutic opportunity.

TurboID reveals the interaction network of VESICLE-INDUCING PROTEIN IN PLASTIDS (VIPPs) in Chlamydomonas reinhardtii

Project description:In Chlamydomonas reinhardtii, VIPP1 and VIPP2 play a role in the sensing and coping with membrane stress and in thylakoid membrane biogenesis. To gain more insight into these processes, we aimed to identify proteins interacting with VIPP1/2 in the chloroplast under ambient and H2O2 stress conditions and chose proximity labeling (PL) for this purpose. While PL with APEX2 and BioID proved to be inefficient, TurboID resulted in significant biotinylation in vivo, which could be enhanced by exogenously added biotin. Using TurboID-mediated PL with VIPP1/2 as baits we could confirm known interactions of VIPP1 with VIPP2, HSP70B and CDJ2. Novel proteins in the VIPP1/2 interaction network can be grouped into proteins involved in the biogenesis of thylakoid membrane complexes and the regulation of photosynthetic electron transport. A third group comprises 11 proteins of unknown function whose genes are upregulated under chloroplast stress conditions. We named these proteins VIPP PROXIMITY LABELING (VPL1-11) and confirmed the proximity of VIPP1 and VPL2 in a reciprocal experiment. Our results demonstrate the robustness of TurboID-mediated PL for studying protein interaction networks in the chloroplast of Chlamydomonas and pave the way for targeted analyses of the functions of VIPPs in thylakoid biogenesis and chloroplast stress responses.
