Molecular chaperones govern proteome health to support cell homeostasis. An essential eukaryotic component of the chaperone system is Hsp90. Using a chemical-biology approach, we characterized the features driving the Hsp90 physical interactome. We found that Hsp90 associated with ∼20% of the yeast proteome using its three domains to preferentially target intrinsically disordered regions (IDRs) of client proteins. Hsp90 selectively utilized an IDR to regulate client activity as well as maintaine ...[more]

Quantification of calcyclin and heat shock protein 90 in sera from women with and without preeclampsia by mass spectrometry

Project description:Maternal serum levels of calcyclin and heat shock protein 90 were compared throughout pregnancy from the first trimester till term among women with preeclampsia (PE) and age-matched normotensive pregnant controls (C). Serum samples from two different studies, a nested case-control study embedded in the Rotterdam periconception cohort and the Lepra Study both conducted at the Erasmus MC in Rotterdam. They were collected in the first, second and third trimester of pregnancy in 43 patients with preeclampsia, consisting of 20 early-onset and 23 late-onset preeclampsia, and 46 normotensive pregnant controls. A serum based 2D LC-MS assay on Parallel Reaction Monitoring mode using a high resolution tribrid mass spectrometer was used to quantify both calcyclin and heat shock protein 90.

Characterizations of HSP90-interacting complex in renal cells using tandem affinity purification and its potential role in kidney stone formation

Project description:Heat shock protein 90 (HSP90) is a highly abundant molecular chaperone that interacts with many other intracellular proteins to regulate various cellular processes. However, compositions of the HSP90-interacting complex remain underinvestigated. This study thus aimed to characterize such complex in human embryonic kidney (HEK293T) cells under normal physiologic state using tandem affinity purification (TAP) followed by protein identification using an ultrahigh-resolution tandem mass spectrometer (Qq-TOF MS/MS). A total of 32 proteins, including four forms of HSP90 and 16 novel HSP90-interacting partners, were successfully identified from this complex using TAP control to subtract non-specific binders. Co-immunoprecipitation followed by immunoblotting and immunofluorescence co-staining confirmed the association of HSP90 with known (HSP70, α-tubulin, and β-actin) and novel (vimentin, calpain-1, and importin-β1) partners. Knockdown of HSP90 by small-interfering RNA (siHSP90) caused significant changes in levels of HSP70, α-tubulin, β-actin, vimentin, and calpain-1, all of which are calcium oxalate (CaOx) crystal-binding proteins that play significant roles in kidney stone formation. Moreover, crystal-binding capability was significantly decreased in siHSP90-transfected cells as compared to non-transfected control and siControl-transfected cells. In summary, we report herein a number of novel HSP90-interacting proteins in renal cells and demonstrate the potential role of HSP90-interacting complex in kidney stone formation.

Post-transcriptional buffering of low nascent RNA transcription by Puf5

Project description:Gene expression is a dynamic process regulated on several layers starting with transcription, mRNA export, translation and finally, mRNA degradation. While subsequent layers heavily influence each other, it is not clear if the most extreme layers, chromatin architecture and mRNA decay are linked. Here, we show that changes in nascent transcription mediated by mutating H3K56 to alanine are buffered at a post-transcriptional level by the Pumilio protein Puf5, which stabilizes transcripts in a context-dependent manner. Depleting Puf5 in an H3K56A background leads to downregulation of its direct targets, largely consisting of ribosomal protein genes. This is followed by a decrease in translation efficiency and finally, cell cycle arrest. Importantly, we show that this phenomenon of post-transcriptional buffering is not only linked to H3K56A, but might be a more widespread phenomenon to ensure physiological mRNA levels and to maintain cellular homeostasis.

Hsp70 and NAC chaperone systems are in close proximity on the ribosome

Project description:To understand the orientation of Hsp70 Ssb on the ribosome in living Saccharomyces cerevisiae cells we incorporated the noncanonical, photoactivatable amino acid p-benzoyl-L-phenylalanine (Bpa) in place of specific individual endogenous amino acids in Ssb1. To identify the proteins to which Ssb1Bpa crosslinked we performed mass spectrometry. The results revealed that Bpa incorporated at the tip of the “lid” subdomain cross linked to the nascent chain associated complex (NAC), while Bpa incorporated into further down the lid crosslinked to ribosomal protein uL29.

Disordered region encodes α-crystallin chaperone activity toward lens client γD-crystallin

Project description:Small heat-shock proteins (sHSPs) are a widely expressed family of ATP-independent molecular chaperones that are among the first responders to cellular stress. Mechanisms by which sHSPs delay aggregation of client proteins remain undefined. sHSPs have high intrinsic disorder content of up to ~60% and assemble into large, polydisperse homo- and hetero-oligomers, making them challenging structural and biochemical targets. Two sHSPs, HSPB4 and HSPB5, are present at millimolar concentrations in eye lens, where they are responsible for maintaining lens transparency over the lifetime of an organism. Together, HSPB4 and HSPB5 compose the hetero-oligomeric chaperone known as α-crystallin. To identify the determinants of sHSP function, we compared the effectiveness of HSPB4 and HSPB5 homo-oligomers and HSPB4/HSPB5 hetero-oligomers in delaying the aggregation of the lens protein γD-crystallin. In chimeric versions of HSPB4 and HSPB5, chaperone activity tracked with the identity of the 60-residue disordered N-terminal regions (NTR). A short 10-residue stretch in the middle of the NTR (“Critical sequence”) contains three residues that are responsible for high HSPB5 chaperone activity toward γD-crystallin. These residues affect structure and dynamics throughout the NTR. Abundant interactions involving the NTR Critical sequence reveal it to be a hub for a network of interactions within oligomers. We propose a model whereby the NTR critical sequence influences local structure and NTR dynamics that modulate accessibility of the NTR, which in turn modulates chaperone activity.

Heat-shock protein 90 globally targets paused promoters and regulates environment-induced gene expression

Project description:In this study we provide evidence that Hsp90 binds chromatin at specific sites close to several TSS in Drosophila S2 cell line. In addition of finding a preference for stalled promoter regions of annotated genes, we uncover many intergenic Hsp90 binding sites coinciding with non-annotated transcription start sites. Interestingly, this set includes promoters for primary transcripts of microRNA genes, thereby expanding the scope of Hsp90 to transcriptional control of many genes. We finally conclude that Hsp90 contacts NelfE and thus regulates pol II pausing. Our Dataset comprises of 1 ChIP-seq sample using chromatin from S2 cells which was immunoprecipitated, using antibodies against Drosophila Hsp90. The two biological replicates are submitted along with the input replicates.

The impact of Bisphenol A on immunity and asthmatic inheritance revealed from a major proteomics study

Project description:Environmental estrogens, such as bisphenol A (BPA) that is normally used in the manufacture of food and beverage containers, pose increasingly worrisome hazards to human and wildlife health. The adverse effects of BPA are multifaceted; while close attention has been paid to their effect on the immune response system, especially the possible etiology of asthma in children and adults. The underlined mechanism of how BPA influences the biological pathways that alters the normal immune response system is unknown. Here, we report to use various proteomics and biological approaches to identify BPA-targeting proteins and protein pathways in human colonic and CD4+T cell lines and CD4+T cells extracted from mouse spleens. The outcomes of this study revealed that the cellular respiration, phagosome maturation and especially the Sirtuin signaling pathways are among the top canonic or KEGG pathways perturbed by BPA and they are proteome-phenotypic inheritable to multi-generations. Most importantly, a protein palmitoyltransferase, ZDHHC1, was identified as one of the top proteins upregulated by BPA; and further, it was found that ZDHHC1 forms a heterodimer with STING. This novel finding constitutes a mechanistic model better describing how BPA and E2, as well as vitamin D3, are engaged in the immune response of asthma by up-regulating the expression of ZDHHC1 through histone modifications and its down-stream STING signaling pathways.

Novel recognition site for polyUb and UBL signals in Rpn1

Project description:Rpn1 is the largest proteasomal receptor for polyubiquitin and shuttle proteins contains one known binding site for polyubiquitin and shuttle proteins. We used a combination of NMR spectroscopy, photo-crosslinking, mass spectrometry, and mutagenesis,to confirm the presence of additional ubiquitin recognition site on RPN1. This novel site is situated in the N-terminal section of Rpn1, a region previously surmised to be devoid of functionality.
