Abstract

Fly by night — and day Gene expression in multicellular organisms fluctuates in line with the day/night cycle, resulting in differential behaviours throughout the day. These changes in expression have been widely studied at the transcriptional and post-translational levels. A further type of circadian-influenced regulation has now been identified in the fruitfly Drosophila. A gene termed twenty-four (twf) is shown to have a role in an under-appreciated aspect of the clock pathway, the translation of a clock component from RNA to protein. The twenty-four protein associates with the mRNA of the clock protein PER, enhancing its translation.
