Exploring Sequence Space to Identify Binding Sites for Regulatory RNA-Binding Proteins

7.1K
Sequence specificity is critical for gene regulation. Regulatory proteins that recognize specific sequences are important for gene regulation. Defining functional binding sites for such proteins is a challenging biological problem. An iterative approach for identification of a binding site for an RNA-binding protein is described here and is applicable to all RNA-binding...

RNA-Protein Pull-Down Assay to Isolate RNA-Binding Proteins via Affinity Extraction

1.2K
This video demonstrates an in vitro RNA pull-down assay to identify RNA-binding proteins (RBPs), which interact with the adenylate-uridylate-rich element (ARE) sequences in mRNA. The target RBPs from a cell lysate are mixed with an RNA probe to form RNA-protein complexes. The complexes are isolated via affinity purification utilizing the affinity of the desthiobiotin label of the RNA probe to a streptavidin-labeled magnetic...
