RNA-binding proteins (RBPs) determine RNA fate from synthesis to decay. Employing two complementary protocols for covalent UV crosslinking of RBPs to RNA, we describe a systematic, unbiased, and comprehensive approach, termed "interactome capture," to define the mRNA interactome of proliferating human HeLa cells. We identify 860 proteins that qualify as RBPs by biochemical and statistical criteria, adding more than 300 RBPs to those previously known and shedding light on RBPs in disease, RNA-bin ...[more]

Global Analysis of Yeast mRNPs

Project description:Proteins regulate gene expression by controlling mRNA biogenesis, localization, translation and decay. Identifying the composition, diversity and function of mRNPs (mRNA protein complexes) is essential to understanding these processes. In a global survey of S. cerevisiae mRNA binding proteins we identified 120 proteins that cross-link to mRNA, including 66 new mRNA binding proteins. These include kinases, RNA modification enzymes, metabolic enzymes, and tRNA and rRNA metabolism factors. These proteins show dynamic subcellular localization during stress, including assembly into stress granules and P-bodies (Processing-bodies). CLIP (cross-linking and immunoprecipitation) analyses of the P-body components Pat1, Lsm1, Dhh1 and Sbp1 identified sites of interaction on specific mRNAs revealing positional binding preferences and co-assembly preferences. Taken together, this work defines the major yeast mRNP proteins, reveals widespread changes in their subcellular location during stress, and begins to define assembly rules for P-body mRNPs. CLIP-seq analysis of Dhh1, Lsm1, Pat1 and Sbp1

Enhancer RNAs stimulate Pol II pause release by harnessing multivalent interactions to NELF

Project description:UV-light-induced protein-RNA cross-linking followed by MS analysis was used to identify RNA-binding regions of enhancer RNAs (eRNAs) to the negative elongation factor (NELF) complex, and NELF as part of the paused elongation complex (PEC) of human RNA polymerase II.

"In-gel cross-linking mass spectrometry (IGX-MS) of proteins and protein complexes"

Project description:Cross-linking mass spectrometry has developed into an important method to study protein structures and interactions. The in-solution cross-linking workflows involve time and sample consuming steps and do not provide sensible solutions for differentiating cross-links obtained from co-occurring protein oligomers, complexes, or conformers. Here we developed a cross-linking workflow combining blue native PAGE with in-gel cross-linking mass spectrometry (IGX-MS). This workflow circumvents steps, such as buffer exchange and cross-linker concentration optimization. Additionally, IGX-MS enables the parallel analysis of co-occurring protein complexes using only small amounts of sample. Another benefit of IGX-MS observed by experiments on GroEL and purified bovine heart mitochondria, is the substantial reduction of artificial over-length cross-links when compared to in-solution cross-linking. We next used IGX-MS to investigate the complement components C5, C6, and their hetero-dimeric C5b6 complex. The obtained cross-links were used to generate a refined structural model of the complement component C6, resembling C6 in its inactivated state. This finding shows that IGX-MS can be used to provide new insights into the initial stages of the terminal complement pathway.

Tissue Transglutaminase 2 has higher affinity for relaxed than for stretched fibronectin fibers

Project description:Chemical cross-linking coupled to mass spectrometry was used to study the interaction between fibronectin (Fn; full-length or gelatin-binding domain fragment = Fn 45) with tissue transglutaminase 2 in oxidized and non-oxidized form. The complexes were cross-linked with disuccinimidyl suberate (DSS) or a combination of pimelic dihydrazide (PDH) in combination with the zero-length cross-linking reagent, DMTMM.

Structural requirements for photo-induced RNA-protein cross-linking

Project description:Cross-linking of isotope-labelled RNA coupled with mass spectrometry (CLIR-MS) was used to study the UV cross-linking behavior of in vitro reconstituted FOX1 RRM in complex with its cognate RNA sequence, the Fox binding element (FBE), (U)GCAUGU. The FBE heptanucleotide was subsequently mutated, and the impact on UV cross-linking and affinity investigated. Cross-linking was performed using irradiation under 254 nm light, relying on the inherent reactivity of ribonucleotides.

Sensitive detection and structural characterisation of UV-induced cross-links in protein-ribonucleic acid complexes using stable isotope labelling and mass spectrometry

Project description:The recently introduced cross-linking of isotope-labelled RNA coupled with mass spectrometry (CLIR-MS) technique enables protein-RNA cross-links to be used as precisely localized distance restraints in de novo structural modelling, but little is known about the structural characteristics of UV-induced cross-links. Here we demonstrate protocol optimizations, and apply the enhanced protocol to a set of model protein-RNA complexes to better characterize the properties of UV-induced protein-RNA cross-links. We use these insights to study a non-canonical protein-RNA interaction between SF3A1 of the U2 snRNP and stem-loop 4 of the U1 snRNP, demonstrating that UV cross-linking and mass spectrometry is a reliable standalone data type for low resolution structural characterizations of protein-RNA interactions.

Identification of human PKD2 interaction partners from cytosolic protein fractions of HeLa cells by affinity enrichment cross-linking/MS

Project description:We investigated the interaction network of human PKD2 in the cytosol as well as in Golgi-enriched subcellular protein fractions, using an affinity enrichment strategy combined with chemical cross-linking/mass spectrometry (MS). Analysis of the subproteomes revealed the presence of distinct proteins in the cytosolic and Golgi fractions. The covalent fixation of transient or weak interactors by chemical cross-linking allowed capturing interaction partners that might otherwise vanish during conventional pull-down experiments. In total, 31 interaction partners were identified for PKD2.
