KPNB1 regulates rhythmic spatio-temporal nuclear import of the PER/CRY complex and is required for negative feedback repression in mammalian and fly clock function.

Computational modelling together with experimental manipulation indicate that the stability and turnover of activated Notch is inextricably linked to the regulation of the pace of segmentation clock gene expression in the presomitic mesoderm.

The gut-released peptide oxyntomodulin mediates the alignment of liver clock gene and metabolic transcript rhythms with the timing of food intake by postprandial induction of hepatic Per gene expression.

Single cell analysis reveals how period differences between cells and cell-to-cell coupling generates the spatial structure of the plant circadian clock.

A seasonal switch to excitatory GABAA signaling dictates how daily clock neurons interact to encode environmental change.

Conditional deletion of Bmal1 in the forebrain/SCN reveals an essential role of a functional master clock in maintaining synchronized and high amplitude rhythms of peripheral clocks.

Molecular clocks that are robust to external fluctuations are vulnerable to internal fluctuations and vice versa.

The myogenic lineage transcription factor, MYOD1, amplifies and works with the core clock factors to support a daily muscle gene expression program.

Alternative splicing provides a mechanism to maintain oscillations of the circadian clock.

In Arabidopsis, a natural variant of the ELF3 protein, which originated in Central Asia, is less likely to accumulate in the nucleus, and causes the circadian clock to run faster and be less responsive to environmental cues.
