MicroRNAs are small, noncoding RNAs that regulate gene expression in eukaryotes. The multipurpose protein hnRNP A1, a well-known factor in the regulation of precursor messenger RNA splicing, has now been implicated in the biogenesis of the microRNA miR-18a, shedding further light on the emerging topic of post-transcriptional regulation of microRNA expression.
