The circadian clock drives daily rhythms in gene expression to control metabolism, behavior, and physiology; while the underlying transcriptional feedback loops are well defined, the impact of alternative splicing on circadian biology remains poorly understood. Here we describe a robust circadian and light-inducible splicing switch that changes the reading frame of the mouse mRNA encoding U2-auxiliary-factor 26 (U2AF26). This results in translation far into the 3′ UTR, generating a C terminus with homology to theDrosophilaclock regulator TIMELESS. This new U2AF26 variant destabilizes PERIOD1 protein, and U2AF26-deficient mice show nearly arrhythmic PERIOD1 protein levels and broad defects in circadian mRNA expression in peripheral clocks. At the behavioral level, these mice display increased phase advance adaptation following experimental jet lag. These data suggest light-inducedU2af26alternative splicing to be a buffering mechanism that limits PERIOD1 induction, thus stabilizing the circadian clock against abnormal changes in light:dark conditions.
