WebJun 15, 2013 · Transcription-Translation Oscillating (TTO) Loop model. In the positive arm of the TTO loop, Clock, and Bmal1 heterodimerize to activate transcription of circadian target genes, including Per (homologs: 1–3), Cry (homologs:1–2), ROR, and Nr1d1(REV-ERB-α).In the negative arm of the TTO loop, Per and Cry are thought to interact and inhibit …
Interaction of circadian clock proteins PER2 and CRY with BMAL1 …
WebDec 26, 2024 · In turn, these negative-feedback arms repress BMAL1/CLOCK heterodimer transactivation function (PER/CRY) or BMAL1 expression (REVERBα/β). The resulting 24-h oscillations in protein expression can be disrupted through environmental disruption (e.g., shift-work schedules) or genetic deletion of core clock components, producing … WebJan 12, 2024 · Here, we show that CRY-PER participates in the displacement-type repression by recruiting CK1δ to the nucleus and mediating an increased local concentration of CK1δ at CLOCK-BMAL1-bound promoters/enhancers and thus promoting the phosphorylation of CLOCK and dissociation of CLOCK-BMAL1 along with CRY from the … how to cape a deer video
