| Rhythmic CLOCK BMAL 1 binding to multiple E box motifs drives circadian Dbp transcription and chromatin transitions . ^^^ Essentially , the activity of the transcription factors BMAL 1 ( also known as MOP 3 ) and CLOCK is rhythmically counterbalanced by Period ( PER ) and Cryptochrome ( CRY ) proteins to govern time of day dependent gene expression . ^^^ Here we show that circadian regulation of the mouse albumin D element binding protein ( Dbp ) gene involves rhythmic binding of BMAL 1 and CLOCK and marked daily chromatin transitions . ^^^ Thus , the Dbp transcription cycle is paralleled by binding of BMAL 1 and CLOCK to multiple extra and intragenic E boxes , acetylation of Lys 9 of histone H 3 , trimethylation of Lys 4 of histone H 3 and a reduction of histone density . ^^^ The rhythmic conversion of transcriptionally permissive chromatin to facultative heterochromatin relies on the presence of functional BMAL 1 CLOCK binding sites . . ^^^ |
