  1. Abstract:

    DNA-protein interactions (DPIs) are critical to all living organisms, particularly in the regulation of gene expression, replication, packing, recombination, and DNA repair, as well as RNA transport and translation. Many laboratory techniques have been developed to study the complex interactions of proteins with DNA, such as chromatin immunoprecipitation (ChIP) assays, DNA electrophoretic mobility shift assay (EMSA), and oligonucleotide pull-down assays. Here we describe an effective approach to identify potential DNA-binding proteins: a pull-down assay using DNA-conjugated beads with a customized competition strategy, which conferred a more effective and efficient approach to determine the interaction between DNA and protein(s), therefore dramatically improving the progress to investigate novel DNA-binding proteins. © 2023.
