转录阻抑物CTCF,也被称为11锌指蛋白或CCCTC结合因子,是由人类CTCF基因编码的转录因子 [1][2]。 CTCF参与多个细胞进程,包括转录调控、绝缘子活性调控、V (D)J重组、染色质结构调控等 [3][4]。 CTCF最早被认为在鸡体内抑制c-myc基因表达。 CTCF蛋白和以CCCTC为核心序列的三个规则间隔重复蛋白相结合,故得名CCCTC结合因子 [5]。 CTCF的主要功能是调控染色质的3D结构 [4]。 CTCF和DNA双链结合形成染色质环,并把DNA锚定在细胞结构上(例如核纤 …
CTCF - Wikipedia
Transcriptional repressor CTCF also known as 11-zinc finger protein or CCCTC-binding factor is a transcription factor that in humans is encoded by the CTCF gene. [5][6] CTCF is involved in many cellular processes, including transcriptional regulation, insulator activity, V (D)J recombination [7] and regulation of chromatin architecture. [8]

CTCF(CCCTC binding factor),是CTCF基因编码的转录因子 [1],与绝缘子的活性相关。 CTCF蛋白在印记调控区域(imprinting control region,ICR)和分化甲基化区域1(differentially-methylated region-1,DMR1)和MAR3结合抑制 胰岛素样生长因子2 (Igf2)基因的过程中起重要作用 [2]。 CTCF与靶顺序因子的结合可阻断增强子和启动子的相互作用。 从而将增强子的活性限制在一定的功能区域。 除了阻断增强子外,CTCF还可作为染色质屏障阻止异染色质的传播。 …
