TranscriptomicsWidespread N6-methyladenosine-dependent RNA Structural Switches Regulate RNA-Protein Interactions
We show that N6-methyladenosine (m6A), the most abundant internal modification in mRNA/lncRNA with still poorly characterized function, alters RNA structure to facilitate the access of RBM for heterogeneous nuclear ribonucleoprotein C (hnRNP C). We term this mechanism m6A-switch. Through combining P...

TranscriptomicsRNA-protein interaction screening for SNORD50A and SNORD50B
Putative RNA-protein interactions with selected snoRNAs were screened using labaled RNA hybridized to a human protein microarray snoRNAs SNORD50A and SNORD50B were in vitro transcribed, labeled with Cy5 and independently hybridized on human protein microarrays. The labeling process was optimized in ...

ProteomicsThe concept of "RNA dependence" - Proteome-wide and quantitative identification of protein interactions dependent on RNA
The general role of RNA in the cell beyond protein biosynthesis is only beginning to emerge with little knowledge about the structural or organizational functions of RNA. In turn, functional non-coding RNAs (ncRNAs) are often identified by their regulation or impact on cellular phenotypes. However, ...

TranscriptomicsIdentification of Proteins Binding Coding and Non-coding Human RNAs using Protein Microarrays
We describe a refined approach to identify new human RNA-protein interactions. In vitro transcribed labeled RNA is bound to ~9,400 human recombinant proteins spotted on protein microarrays. This approach identified 137 RNA-protein interactions for 10 human coding and non-coding RNAs, including an in...

TranscriptomicsMapping interactions for the TNIP2 hub protein
This experiment analyzes the set of RNAs copurifying with the protein TNIP2 (amino acids 196-346) HEK293 cells were transfected with constructs expressing either Halo tag (controls) or Halo-TNIP2 196-346. Total RNA was purified from an aliquot of the whole cell extract (Input samples). Halo-tagged p...

TranscriptomicsRocaglates convert DEAD-box protein eIF4A into a sequence-selective translational repressor
Rocaglamide A (RocA) typifies a class of protein synthesis inhibitors that selectively kill aneuploid tumor cells and repress translation of specific mRNAs. RocA targets eukaryotic initiation factor 4A (eIF4A), an ATP-dependent DEAD-box RNA helicase; its mRNA selectivity is proposed to reflect highl...

TranscriptomicsIntegrative regulatory mapping indicates that the RNA-binding protein HuR (ELAVL1) couples pre-mRNA processing and mRNA stability [sequence data]
RNA-binding proteins coordinate the fates of multiple RNAs, but the principles underlying these global interactions remain poorly understood. We elucidated regulatory mechanisms of the RNA-binding protein HuR, by integrating data from diverse high-throughput targeting technologies, specifically PAR-...

TranscriptomicsControlling for gene expression changes in transcription factor protein networks.
The development of affinity purification technologies together with mass spectrometric analyses of the purified protein mixtures (AP-MS) has been used both to identify new protein-protein interactions and to define the subunit composition of protein complexes. Transcription factor protein interactio...
