Transcription factors (TFs) are proteins that regulate the gene expression programs and the identity of each cell by encountering numerous binding partners in the nucleus to turn transcription on or ...

The TF binding sites shown are for illustrative purposes but reflect ... The role of XPB/Ssl2 dsDNA translocation processivity in transcription start-site scanning. J Mol Biol 2021; 433: 166813. Rimel ...

Often they indicate sequence-specific binding sites for proteins such as nucleases and transcription factors (TF). Others are involved ... transcription initiation site of Escherichia coli promoters.

These competition studies demonstrate that the NoShift Assay can effectively differentiate between site-specific binding (to specific TF sequences) and nonspecific binding even when a lower molar ...
