WebCTCF DNA-binding is sensitive to DNA methylation, a mark that determines selection of the imprinted allele (maternal vs. paternal) (1). The various functions of CTCF are regulated by at least two different post-translational modifications. Poly (ADP-ribosyl)ation of CTCF is required for insulator function (8). Web5.1 CTCF genome organizer and the cohesin complex. CTCF (CCCTC-binding factor) is a multiple zinc finger protein that exerts diversified functions under different genomic contexts. CTCF was first isolated and cloned on the basis of its ability to bind to highly divergent 50–60 bp sequences within the promoter region of the chicken Myc gene ...

WebThe insulator transcription factor CTCF that is usually involved in boundary elements is a key regulator in the Igf2–H19 imprinted region (Bartolomei, 2009; Fig. 2.3A).When the … WebLoss of this stable maternal transcript was temporally associated with loss of CTCF protein expression, apoptosis of the developing embryo, and failure to further develop an inner cell mass and trophoectoderm ex vivo. This indicates that CTCF expression is critical to early embryogenesis and loss of its expression rapidly leads to apoptosis at ... WebJun 1, 2024 · CTCF facilitates the transcription as a transcriptional activator (Fig. 2 A), e.g. in promoter of the amyloid β-protein precursor (APP) gene [20].There is a nuclear factor binding site APBβ located between positions 93 and 82 in the promoter to carry out an in-vitro transcriptional link between CTCF and APP promoter transcriptional activity through … csld.ca gov
