WebJan 14, 2024 · The 3D structures of chromosomes in vertebrate cells play a critical role in nearly all nuclear processes, including transcriptional control of gene expression, replication of DNA, repair of DNA damage, and splicing of messenger RNA (1–4).A key player in chromatin organization is the CCCTC-binding factor (CTCF), an 11-zinc finger (11ZF) … WebNov 3, 2011 · Here we provide the first evidence that a DNA-binding protein, CCCTC-binding factor (CTCF), can promote inclusion of weak upstream exons by mediating local RNA polymerase II pausing both in a mammalian model system for alternative splicing, CD45, and genome-wide. We further show that CTCF binding to CD45 exon 5 is …
