Method Of Purifying RNA Binding Protein-RNA Complexes

The present invention provides methods for purifying RNA molecules interacting with an RNA binding protein (RBP), and the use of such methods to analyze a gene expression profile of a cell. The invention also provides sequences of RNA molecules that mediate binding to an RBP, proteins encoded by the sequences, a method of identifying the sequences, and the use of the sequences in a screen to identify bioactive molecules. The invention also provides RNA motifs found among the sequences and compounds that bind the RNA motifs. In addition, the invention provides methods of treating diseases associated with a function of an RNA binding protein.
