Utilization of Stability-based Proteomics for the Investigation of Structured RNA-protein Interactions

ABSTRACT: The stability of proteins from rates of oxidation (SPROX), thermal protein profiling (TPP) methods as well as triple helix pulldowns with LC-MS/MS readouts are used to identify the protein targets of three RNA ligands, the MALAT1 triple helix (TH), a viral stem loop (SL), and an unstructured RNA (PolyU) in LNCaP nuclear lysate. This work establishes a novel platform for the global discovery and interrogation of RNA-protein interactions that is generalizable to numerous biological contexts and RNA targets.

Identification and Characterization of a Class of MALAT1-like Genomic Loci

Project description:The MALAT1 (Metastasis-Associated Lung Adenocarcinoma Transcript 1) gene encodes a non-coding RNA that is processed into a long nuclear retained transcript (MALAT1) and a small cytoplasmic tRNA-like transcript (mascRNA). Using a RNA sequence- and structure-based covariance model, we identified more than 130 genomic loci in vertebrate genomes containing the MALAT1 3’-end triple helix structure and its immediate downstream tRNA-like structure, including 44 in the green lizard Anolis carolinensis. Structural and computational analyses revealed a coevolution of the 3’-end module. MALAT1-like genes in Anolis carolinensis are highly expressed in adult testis, thus we named them testis-abundant long noncoding RNAs (tancRNAs). TancRNA loci produce multiple small RNA species, including piRNAs, from the antisense strand. The coevolved 3’-end of tancRNAs serve as potential targets for the PIWI-piRNA complex. Thus, we have identified an evolutionarily conserved class of lncRNAs with similar structural constraints, post-transcriptional processing, subcellular localization and a distinct function in spermatocytes.

Quantitative Proteomics to identify nuclear RNA-binding proteins of Malat1

Project description:The long non-coding RNA Malat1 has been implicated in several human cancers, while the mechanism of action is not completely understood. As RNAs in cells function in the context of RBPs identification of their RNA-binding proteins can shed light on their functionality. We here performed quantitative interactomics of 14 non-overlapping fragments covering the full length of Malat1 to identify possible nuclear interacting proteins. Overall, we identified 35 candidates including 14 already known binders, which are able to interact with Malat1 in the nucleus. Furthermore, the use of fragments along the full-length RNA allowed us to reveal two hotspots for protein binding, one in the 5’-region and one in the 3’-region of Malat1. Our results provide confirmation on previous RNA-protein interaction studies and suggest new candidates for functional investigations.

Distinct Function for ASCL1 and NEUROD1 in Pulmonary Neuroendocrine Tumors (RNA-seq)

Project description:Small cell lung carcinoma (SCLC) and large cell neuroendocrine carcinoma (LCNEC) are high-grade pulmonary neuroendocrine tumors. The neural basic helix-loop-helix (bHLH) transcription factors ASCL1 and NEUROD1 have been shown to play crucial roles in promoting the malignant behavior and survival of human SCLC cell lines. In this study, we find ASCL1 and NEUROD1 identify distinct neuroendocrine tumors, bind distinct genomic loci, and regulate mostly distinct genes. ASCL1 and NEUROD1 are often bound in super-enhancers that are associated with highly expressed genes in their respective SCLC cell lines suggesting different cell lineage of origin for these tumors. ASCL1 targets oncogenic genes such as MYCL1, RET, and NFIB, while NEUROD1 targets the oncogenic gene MYC. Although ASCL1 and NEUROD1 regulate different genes, many of these gene targets commonly contribute to neuroendocrine and cell migration function. ASCL1 in particular also regulates genes in the NOTCH pathway and genes important in cell-cycle dynamics. Finally, we demonstrate ASCL1 but not NEUROD1 is required for SCLC and LCNEC tumor formation in current in vivo genetic mouse models of pulmonary neuroendocrine tumors RNA-seq analysis performed on two ASCL1high and two NEUROD1high human SCLC cell lines to identify gene expression patterns in these cells. Also, we performed RNA-seq in mouse neuroendocrine lung tumors obtained from Trp53;Rb1;Rbl2 triple knockout model mice treated with Adeno-CMVCRE intratracheally.

RIP-seq data for CCNT1

Project description:To demonstrate RIPSeeker program that is developed for RIP-seq analyses, we generated RIP-seq data corresponding to the protein CCNT1 in HEK293 cell line using standard RIP-seq protocols described in Zhao et al., (2010). We performed two in-house RIP-seq experiments both for CCNT1 in human HEK293 cells. Briefly, we generated tagged CCNT1 using a triple tag system that supports lentiviral stable expression and mammalian affinity purification (MAPLE) Mak et al (2010). The HEK293 cells stably expressing tagged CCNT1 was purified by M2 agarose beads, followed by RNA extraction by Trizol. The library synthesis was carried out according to the RIP-seq protocol described in Zhao et al., (2010) except that one of the two experiments was done with non-strand-specific sequencing.

lncRNA MALAT1 interactome - Quantitative proteomics reveals that long non-coding RNA MALAT1 interacts with DBC1 to regulate p53 acetylation

Project description:Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a long non-coding RNA (lncRNA) that was first discovered as a prognostic marker for lung cancer metastasis. MALAT1 has been implicated in the tumorigenesis of numerous tumor types. To further delineate the underlying molecular mechanism, we established a high-throughput strategy to characterize the interacting proteins of MALAT1 by combining RNA pull down, quantitative proteomics, bioinformatics analysis, and experimental validation.

RBPMS mediates smooth muscle specific alternative splicing via oligomerization and modulation of trans factor recruitment

Project description:RBPMS regulate splicing decisions by modulating the transcript-bound proteome. This experiment aims to investigate the proteome assembled on an experimental RNA, TM3 transcript, in human Hela nuclear extract under the various conditions, ± ATP and ± RBPMS. The model RNA is tethered on amylose bead via a protein, MPB-MS2. After pull-down, the protein-RNA complexes are eluted from the beads with maltose. The sample series "N" and "NA" are two negative control conditions. "B" and "R" are sample series of two experimental conditions.

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.
