RNA-RNA Interaction Analysis

Background

In addition to its mediating role in protein synthesis, RNA is a versatile molecule that directly participates in the regulation of most cellular processes, including epigenetic control, gene transcription, translation, RNA turnover, and also plays a key role in cell development and proliferation. In the past few decades, it has been shown that RNA works by interacting with different molecules (such as protein, nucleic acid). For example, hundreds of RNA-binding proteins (RBP) have been found in prokaryotes and eukaryotes, another important type of RNA interaction is between two RNA molecules, the RNA-RNA interaction (RRI). For example, during splicing, small nuclear RNAs (snRNAs) can recognize the intron region of precursor messenger RNAs (pre-mRNAs), which is a key step in determining RNA splicing products. A large number of such examples highlight the importance of RRI in regulating life activities.

There are many techniques used to identify and analyze RRI. However, due to the complexity and technical limitations of RRI, any type of method is not complete. Creative Proteomics has developed an RRI platform that includes multiple technologies, and fully combines experiments and calculations to explore their regulatory effects in biology and medicine.

Services

In order to study RRI, Creative Proteomics has developed a series of technologies with different strengths and different dimensions, including but not limited to the following aspects.

• Traditional biophysical, biochemical and cellular methods, including EMSA, SPR, FRET, Co-sedimentation, yeast RNA-hybrid system, etc. Usually, these methods can only detect interactions at the molecular level, but cannot reveal the exact areas that mediate the interactions between molecules.
• High-throughput and targeted methods, such as CLASH, hiCLIP, RAP, etc.
• Large-scale identification methods at the transcriptome level, including SPLASH, LIGR-seq, MARIO, etc. Such methods can help us discover many unknown RRIs, and can greatly improve our understanding of RNA interactomes.
