Comprehensive discovery of endogenous Argonaute binding sites in Caenorhabditis elegans

MicroRNAs are small RNAs involved in regulation of cognate mRNAs, but predicting their exact targets has been difficult. Using a cross-linking immunoprecipitation technique, a comprehensive examination of endogenous mRNA target sites associated with the C. elegans Argonaute family member ALG-1 is now presented.
