The balance of power in RNA trafficking

In the past two years, several different RNA trafficking pathways have been characterized in oligodendrocytes; similar trafficking pathways have been discovered in neuronal and retroviral systems; co-assembly of multiple diff erent RNAs into the same granules has been analyzed as a mechanism for coor dinating gene expression; and a new hypothesis for RNA trafficking, based o n the balance of power between kinesin and dynein in individual RNA granule s, has been proposed.
