In this video, we describe the systematic evolution of ligands by the exponential enrichment (SELEX) method to identify specific RNA-binding sequences for a target protein of interest. The protein is incubated with a large pool of randomized RNA sequences, and the protein-binding RNA sequences are isolated, PCR-amplified, and sequenced to identify their protein-binding sites.

The spatial arrangement of RNA-binding proteins on a transcript is a key determinant of post-transcriptional regulation. Therefore, we developed individual-nucleotide resolution UV crosslinking and immunoprecipitation (iCLIP) that allows precise genome-wide mapping of the binding sites of an RNA-binding protein.
FAQs
Complementary base pairing, hydrogen bonding, and recognition of particular RNA sequences or folded structures determine where contacts are likely to form. These molecular features help select interaction partners and establish localized regulatory sites. Differences in sequence or structure can therefore influence whether an interaction changes RNA stability, localization, processing, or translation.
Their effects extend across several stages of post-transcriptional control. An interaction may alter how long an RNA remains stable, where it is localized, how it is processed, or how efficiently it is translated. Because these outcomes affect the use of genetic information without changing transcription itself, interaction zones can connect molecular contacts with changes in gene expression.
A folded RNA structure can create a recognizable molecular surface or expose particular nucleic acid features for interaction. As a result, recognition may depend on more than a simple sequence match. Structural differences can help determine which RNA, protein, or nucleic acid partner contacts a region, shaping the regulatory consequence of that interaction.
Noncoding RNAs provide an important context for examining regulatory interactions because their functions can depend on contacts with other RNAs, proteins, or nucleic acids. Studying these zones helps place noncoding RNA activity within broader regulatory networks and clarifies how such molecules contribute to post-transcriptional control of gene expression.
Mapping these regions can identify where molecular contacts occur and connect those contacts with changes in RNA behavior. The resulting information can clarify regulatory networks, noncoding RNA function, and post-transcriptional control. It also helps researchers relate localized interactions to outcomes such as altered RNA stability, localization, processing, or translation.
Genetic disease mechanisms may involve disrupted regulation of RNA rather than changes limited to transcription. By examining interaction zones, researchers can investigate how altered molecular contacts might affect RNA stability, localization, processing, or translation. This connects RNA-level regulation with broader genetic disease research and can highlight regulatory relationships that warrant further study.
Characterizing these interactions can reveal regulatory features associated with RNA behavior and gene-expression control. That information may support research into RNA-based diagnostics or therapeutics by identifying interaction patterns relevant to disease mechanisms or post-transcriptional regulation. The value lies in linking molecular interaction maps with measurable regulatory functions and potential intervention strategies.
