Where this comes from

Abstract

MicroRNAs interact with Argonaute proteins to guide posttranscriptional gene silencing. Eiring et al. (2010) now show that miR-328 has a second function, acting as a decoy by binding to hnRNP E2 and lifting its translational repression of an mRNA involved in myeloid cell differentiation.
