Significant recent advances in structural biology, particularly in the field of cryoelectron microscopy, have dramatically expanded our ability to create structural models of proteins and protein complexes. However, many proteins remain refractory to these approaches because of their low abundance, low stability, or-in the case of complexes-simply not having yet been analyzed. Here, we demonstrate the power of using cross-linking mass spectrometry (XL-MS) for the high-throughput experimental ass ...[more]

Structural analysis of the PTEN:P-Rex2 signaling node reveals how cancer-associated mutations coordinate to hyperactivate Rac1

Project description:The PTEN:P-Rex2 complex is a commonly mutated signaling nodes in metastatic cancer. The dual-specificity phosphatase PTEN canonically functions as a tumour suppressor by hydrolysing PI(3,4,5)P3 to PI(4,5)P2 to inhibit PI3K-AKT signaling. P-Rex2 is a RhoGTPase guanine nucleotide exchange factor activated by both Gβγ and PI(3,4,5)P3 downstream of G protein-coupled receptor and receptor tyrosine kinase signaling. Assembly of the PTEN:P-Rex2 complex inhibits the activity of both proteins, and its dysregulation can drive PI3K-AKT signaling and cell proliferation. However, structural insights into both PTEN:P-Rex2 complex assembly and its dysregulation by cancer-associated mutations remain limited. Here, using crosslinking mass spectrometry and functional studies, we provide mechanistic insights into PTEN:P-Rex2 complex assembly and co-inhibition. PTEN is anchored to P-Rex2 by interactions between the PTEN C-terminal tail PDZ-interacting motif and the second PDZ domain of P-Rex2. This interaction bridges PTEN across the P-Rex2 surface, occluding PI(3,4,5)P3 hydrolysis. Conversely, PTEN both allosterically promotes an autoinhibited P-Rex2 conformation and occludes Gβγ binding. These insights allow us to define a new gain-of-function class of cancer mutations within the PTEN:P-Rex2 interface that uncouples PTEN inhibition of Rac1 signaling. In addition, we observe synergy between PTEN deactivating and P-Rex2 truncation mutations that combine to drive Rac1 activation to a greater extent than either single mutation alone.

Structural analysis of neurofibromin by crosslinking mass spectrometry

Project description:Neurofibromin (NF1) is a fundamental inhibitor of cell growth that is conserved from yeast to humans. NF1 negatively regulates oncogenic RAS proteins by accelerating the hydrolysis of RAS-bound GTP. This activity blocks growth factor signalling upstream of both mitogen-activated protein kinase (MAPK) and phosphoinositide 3-kinase (PI3K) pathways. However, the structure and regulatory mechanisms of NF1 have remained elusive. Here we report crosslinking mass spectrometry analysis of the 320 kDa NF1 protein.

Characterization of the platelet transcriptome by RNA sequencing in patients with acute myocardial infarction.

Project description:Recent technological advances have made transcriptome sequencing (RNA-seq) possible in cells with low RNA copy number including platelets. Resulting studies have used RNA-seq in platelets isolated from healthy individuals to characterize the platelet transcriptome. However, platelets, possibly through gene expression changes, contribute to the etiology of and response to cardiovascular disease and events. To address this, we performed the largest human platelet RNA-seq analysis to date in 34 platelet samples: 16 ST-segment elevation myocardial infarction (STEMI), 16 non-STEMI (NSTEMI), and 2 controls. RNA-seq of platelet samples from 34 individuals: 16 with ST-elevation myocardial infarction (STEMI), 16 with non-STEMI, and 2 non-myocardial infarction controls

Comprehensive identification of crosslinked peptides from methyltransferase Hmt1 and its substrate Npl3: use of multiple crosslinkers, mass spectrometry approaches and software platforms

Project description:Chemical-Crosslinking Mass Spectrometry (XLMS) using MS-cleavable crosslinkers is fast becoming an established technique in the study of protein-protein interactions for both small and large scale samples. With the increased uptake of XLMS as a technique, different combinations of crosslinker types, fragmentation strategies and analysis programs are being applied to a diverse array of biological samples. This study is focused on understanding how the three variables of an XLMS experiment – crosslinker type, fragmentation and program – could generate differences in identifications, leading to increased biological coverage of a sample. Here we probe for the first time, the known enzyme:substrate interaction between yeast arginine methyltransferase Hmt1p and its substrate, heterologous nucleolar protein Npl3p. We use this known interaction as a platform to compare two analysis programs, MeroX and XlinkX2.0, using two crosslinker types, DSSO and DSBU, and two mass-spectrometry fragmentation strategies, CID/ETD and SteppedHCD. Through these we also compare different algorithm strategies, Precursor and Reporter-Ion, as well as assess the impact of restricting data searches to lysine only crosslinks versus the inclusion of serine, threonine and tyrosine as reactive residues. From this analysis we show direct evidence of Hmt1p in contact with its known methylation sites on Npl3p, the intrinsically disordered “SRGG” region. We also show through our multi-crosslinker, multi-fragmentation and multi-software approach that two approaches leads to greater understanding and depth of a crosslinked sample, and this is due to some combinations of experimental variables creating greater coverage of crosslinks than others.

FOXF1 promoter-putative enhancer chromatin looping

Project description:To determine if there is a physical interaction between the FOXF1 promoter and putative enhancer sequences ~250kb upstream of the promoter chromosome conformation capture-on-chip (4C) analysis was performed. An unanticipated and tremendous amount of the non-coding sequences of the human genome are transcribed. Long non-coding RNAs (lncRNAs) are non-protein coding transcripts longer than 200 nucleotides and their functions remain enigmatic. We demonstrate that deletions of lncRNA genes cause a lethal lung developmental disorder, Alveolar Capillary Dysplasia with Misalignment of Pulmonary Veins (ACD/MPV), with parent of origin effects. We identify non-coding overlapping deletions 250 kb upstream to FOXF1 in nine patients with ACD/MPV that arose de novo specifically on the maternally inherited chromosome and delete a fetal lung-specific EST, part of an lncRNA. These deletions define distant cis-regulatory region that harbors a differentially methylated CpG island, binds GLI2 depending on the methylation status of this CpG island, and physically interacts with and up-regulates the FOXF1 promoter, consistent with the absence of the fetal lung-transcribed lncRNA perturbing FOXF1 regulation. LncRNA-mediated chromatin interactions may be responsible for position effect phenomenon and potentially cause many disorders of human development. 4C analysis using 16q24.1 specific 3x720K arrays demonstrated physical interaction between the FOXF1 promoter and distant putative regulatory sequences, about 250 kb upstream in human pulomonary microvascular endothelial cells; 2 biological replicates performed; this chromatin looping was not detected in lymphoblasts that do not express FOXF1 and hence serve as a negative control.

Mass spectrometric analysis of membrane protein topology

Project description:Here we made an attempt to obtain partial structural information on the topology of multispan integral membrane proteins of yeast by isolating organellar membranes, removing peripheral membrane proteins at pH 11.5 and introducing chemical crosslinks between vicinal amino acids either using homo- or hetero-bifunctional crosslinkers. Proteins were digested with specific proteases and the products analysed by mass spectrometry. Dedicated software tools were used together with filtering steps optimized to remove false positive crosslinks. In proteins of known structure, crosslinks were found only between loops residing on the same side of the membrane. As may be expected, crosslinks were mainly found in very abundant proteins. Our approach seems to hold to promise to yield low resolution topological information for naturally very abundant or strongly overexpressed proteins with relatively little effort.
