Updated project metadata. To dissect how diurnal rhythms affect key functions such as transcription or chromatin remodeling, we quantified the temporal nuclear accumulation of proteins and phosphoproteins from mouse liver by SILAC-based MS. Protein extracts from isotope labelled mice liver nuclei were used as a reference and mixed with extracts from animals collected every 3h for 45h total. Total protein levels were analysed together with phosphopeptides after enrichment (see separate dataset for phospho data).
