title: A CRY in the Night.
abstract: CRY1 is essential for normal circadian clock function, but its transcriptional regulation by the clock has not been considered an important feature for its function. However, reporting in Cell, Ukai-Tadenuma et al. (2011) now show that rhythmic Cry1 expression in the early night is critical for clock function.
