Abstract

Regulatory RNAs in bacteria are known to act by base pairing with other RNAs. Interactions between two partner RNAs can be investigated by electrophoretic mobility shift assays. The regions predicted to be engaged in base pairing are analyzed by introducing mutations in one RNA that prevent RNA-RNA complex formation. Next, base pairing is restored by introducing complementary mutations in its partner RNA. Here, we describe the mutational strategy and experimental methods used to validate specific base pairing between two RNA species.
