Physical interaction between components of DNA mismatch repair and nucleotide excision repair.
Nucleotide excision repair (NER) and DNA mismatch repair are required for some common processes although the biochemical basis for this requirement is unknown. Saccharomyces cerevisiae RAD14 was identified in a two-hybrid screen using MSH2 as "bait," and pairwise interactions between MSH2 and RAD1, RAD2, RAD3, RAD10, RAD14, and RAD25 subsequently were demonstrated by two-hybrid analysis. MSH2 c...
متن کاملMismatch repair and nucleotide excision repair proteins cooperate in the recognition of DNA interstrand crosslinks
DNA interstrand crosslinks (ICLs) are among the most cytotoxic types of DNA damage, thus ICL-inducing agents such as psoralen, are clinically useful chemotherapeutics. Psoralen-modified triplex-forming oligonucleotides (TFOs) have been used to target ICLs to specific genomic sites to increase the selectivity of these agents. However, how TFO-directed psoralen ICLs (Tdp-ICLs) are recognized and ...
متن کاملMammalian DNA nucleotide excision repair reconstituted with purified protein components
Nucleotide excision repair is the principal way by which human cells remove UV damage from DNA. Human cell extracts were fractionated to locate active components, including xeroderma pigmentosum (XP) and ERCC factors. The incision reaction was then reconstituted with the purified proteins RPA, XPA, TFIIH (containing XPB and XPD), XPC, UV-DDB, XPG, partially purified ERCC1/XPF complex, and a fac...
متن کاملRepair of triplex-directed DNA alkylation by nucleotide excision repair.
Triplex-forming oligonucleotides (TFOs) are being investigated as highly specific DNA binding agents to inhibit the expression of clinically relevant genes. So far, they have been shown to inhibit transcription from the HER-2/neu gene in vitro, whereas their use in vivo has been studied to a limited extent. This study uses a TFO-chlorambucil (chl) conjugate capable of forming site-specific cova...
متن کاملDNA Repair: Nucleotide excision–repair in the test tube
The eukaryotic nucleotide excision-repair pathway has been reconstituted in vitro, an achievement that should hasten the full enzymological characterization of this highly complex DNA-repair pathway.
