RNA localization is important in diverse biological process including establishment of polarity. This study has focused on migrating fibroblasts that polarize to form a leading edge and tail, in a process that involves assymetric distribution of RNAs. On a genome-wide scale RNAs that are localized to cell protrusions are identified. Through their 3' UTRs, these transcripts are anchored in granules concentrated at the plus end of microtubules and associate with the APC tumour suppressor.
