WebDec 17, 2024 · CLOCK and BMAL1 also regulate the expression of the Nr1d1/2 genes, which encode the nuclear receptors REV-ERBα/β, respectively. These nuclear receptors rhythmically repress the transcription of Bmal1 and Nfil3, two genes that are activated by retinoic acid-related orphan receptor-α/β (RORα/β). WebApr 7, 2024 · Yang W, Kang X, Liu J, Li H, Ma Z, Jin X, et al. Clock gene Bmal1 modulates human cartilage gene expression by crosstalk with Sirt1. Endocrinology. …
WebThe activation of BMAL1–CLOCK target genes depends on the phosphorylation status of BMAL1, which in turn is determined by the balance of phosphorylation by protein … WebAug 1, 2024 · CLOCK/BMAL1 also regulates expression of additional clock-controlled genes, such as RORA and Rev-erb, which, in turn, regulate expression of BMAL1 through binding to ROR response elements (RORE). Thus, this autoregulatory network consisting of positive and negative transcription-translation feedback loops confer daily rhythmicity for ...
WebApr 4, 2024 · The protein encoded by this gene plays a central role in the regulation of circadian rhythms. The protein encodes a transcription factor of the basic helix-loop-helix (bHLH) family and contains DNA binding histone acetyltransferase activity. The encoded protein forms a heterodimer with ARNTL (BMAL1) that binds E-box enhancer elements … WebOct 15, 2010 · CLOCK and BMAL1 are members of the basic helix–loop–helix (bHLH)/PAS family of transcription factors that form a heterodimeric complex and then activate clock gene expression by binding to E-box elements located in the upstream regulatory region of target genes such as Per1 and Per2.
WebJul 20, 2024 · Genetic deletion of the circadian transcription factor Bmal1 (brain and muscle ARNT-like factor; gene symbol Arntl) in mice completely ablates circadian clock function ( Bunger et al., 2000) and has effects on sleep that include: increased total sleep amount, increased non-rapid eye movement (NREM) sleep intensity and reduced ability to …
