Adiponectin signaling integrates metabolic state information to regulate circadian clock function in hypothalamic appetite regulating centers, food intake rhythms, and body weight.
The muscle circadian clock regulates RNA-binding motif 20 (Rbm20) gene expression, providing a novel mechanism for titin splicing and isoform expression with implications for muscle structure and function.

The affinity of circadian repressors CRY1 and CRY2 for their cognate transcription factor CLOCK:BMAL1 is regulated by differential dynamics at the serine loop and interactions with the PER2 corepressor.
Cellular genetics highlights differences in protein catabolism in general, and the COP9 signalosome in particular, as one major source of human cellular circadian variation.
Detailed structural analysis of NPAS1-ARNT and NPAS3-ARNT complexes, and further comparisons with other bHLH-PAS protein structures, show that this family of mammalian transcription factors have distinct ligand-binding pockets within their molecular architectures.
X-ray crystallography reveals the structural framework for understanding the function of mammalian transcriptional repression in the cellular circadian clock.

A gene that codes for a transcription factor that is involved in lipid and carbohydrate metabolism also has a role in the regulation of circadian rhythms.
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.
