A genetic in vivo system to detect asymmetrically distributed RNA.


ABSTRACT: Many RNAs show polarized or otherwise non-random subcellular distributions. To create a method for genome-wide genetic screens for RNAs with asymmetric subcellular distributions, we have combined methods for gene tagging and live imaging of messenger RNA (mRNA). A pilot screen in a highly polarized, differentiated cell in the Drosophila larva, the branched terminal cell of the tracheal system, demonstrates the feasibility of the method for identifying new asymmetrically localized mRNAs in vivo.
