Abstract
microRNAs (miRNAs) serve as post-transcriptional regulators of gene expression, by guiding effector complexes (miRNPs) to target RNAs. Although considerable progress has been made in computational methods to identify miRNA targets, only a relatively limited assessment of their ability to function in vivo has been reported. Here we describe an alternative approach to miRNA target identification based on a biochemical method for purifying miRNP complexes with associated miRNAs and bound mRNA targets. Microarray analysis revealed a high degree of enrichment for miRNA complementary sites in the 3'UTRs of the miRNP-associated mRNAs. mRNAs specifically associated with an individual miRNA were identified by comparing the miRNP-associated mRNAs from wild-type flies and mutant flies lacking miR-1, and their regulation by the miRNA was validated. This approach provides a means to identify functional miRNA targets based on their physical interaction in vivo.
