    Inhibition of DNA binding proteins by oligonucleotide-directed triple helix formation (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-08-18
    Description: Oligonucleotides that bind to duplex DNA in a sequence-specific manner by triple helix formation offer an approach to the experimental manipulation of sequence-specific protein binding. Micromolar concentrations of pyrimidine oligodeoxyribonucleotides are shown to block recognition of double helical DNA by prokaryotic modifying enzymes and a eukaryotic transcription factor at a homopurine target site. Inhibition is sequence-specific. Oligonucleotides containing 5-methylcytosine provide substantially more efficient inhibition than oligonucleotides containing cytosine. The results have implications for gene-specific repression by oligonucleotides or their analogs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maher, L J 3rd -- Wold, B -- Dervan, P B -- New York, N.Y. -- Science. 1989 Aug 18;245(4919):725-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2549631" target="_blank"〉PubMed〈/a〉

    Sequence-specific cleavage of double helical DNA by triple helix formation (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-10-30
    Description: Homopyrimidine oligodeoxyribonucleotides with EDTA-Fe attached at a single position bind the corresponding homopyrimidine-homopurine tracts within large double-stranded DNA by triple helix formation and cleave at that site. Oligonucleotides with EDTA.Fe at the 5' end cause a sequence specific double strand break. The location and asymmetry of the cleavage pattern reveal that the homopyrimidine-EDTA probes bind in the major groove parallel to the homopurine strand of Watson-Crick double helical DNA. The sequence-specific recognition of double helical DNA by homopyrimidine probes is sensitive to single base mismatches. Homopyrimidine probes equipped with DNA cleaving moieties could be useful tools for mapping chromosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moser, H E -- Dervan, P B -- GM 35724/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Oct 30;238(4827):645-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Chemistry and Chemical Engineering, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3118463" target="_blank"〉PubMed〈/a〉

    Echinomycin binding sites on DNA (1984)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1984-09-14
    Description: The preferred binding sites of echinomycin on DNA can be determined by a method called "footprinting." A 32P end-labeled restriction fragment from pBR322 DNA is protected by binding to echinomycin, and cleaved by a synthetic DNA cleaving reagent, methidiumpropyl--EDTA . Fe(II); the DNA cleavage products are then subjected to high-resolution gel analyses. This method reveals that echinomycin has a binding site size of four base pairs. The strong binding sites for echinomycin contain the central two-base-pair sequence 5'-CG-3'. From an analysis of 15 echinomycin sites on 210 base pairs of DNA, key recognition elements for echinomycin are contained in the sequences (5'-3') ACGT and TCGT (A, adenine; C, cytosine; G, guanine; T, thymine).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van Dyke, M M -- Dervan, P B -- GM-07616/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1984 Sep 14;225(4667):1122-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6089341" target="_blank"〉PubMed〈/a〉
