WebAug 28, 2024 · Repression of CLOCK:BMAL1 is in part achieved through rhythmic changes to BMAL1:CRY1 affinity as well as a high affinity interaction between PER2:CRY1 which mediates CLOCK:BMAL1 displacement from DNA. Finally, stochastic modelling of these data reveals a dual role for PER:CRY complexes in which increasing concentrations of … WebMar 3, 2024 · 哺乳动物的昼夜节律基于负反馈通路,其中隐花色素cry1和cry2对其他生物钟基因的转录抑制作用是该机制的核心,并可进一步反馈抑制转录激活因子clock和bmal1的表达。cry1作为有效的转录抑制因子,可单独维持细胞的昼夜节律[47]。 ...
