title: Screening in vivo for RNA-binding peptides from combinatorial libraries.
abstract: We have modified a previously developed genetic assay system for RNA-polypeptide interactions in a attempt to more readily identify RNA-binding peptides. The first modification involved the design of a "complex" library that would contain a variety of RNA-binding polypeptides. The second modification involved the use of neomycin phosphotransferase (NPT II) as the reporter gene, therefore allowing "selection" of RNA-binding peptides by kanamycin resistance. The improved screening system should allow the identification of peptides that bind to a variety of RNA structures.
