The Smc5-Smc6 heterodimer associates with DNA through several independent binding domains
The Smc5-6 complex is required for the maintenance of genome integrity through its functions in DNA repair and chromosome biogenesis. However, the specific mode of action of Smc5 and Smc6 in these processes remains largely unknown. We previously showed that individual components of the Smc5-Smc6 complex bind strongly to DNA as monomers, despite the absence of a canonical DNA-binding domain (DBD...
متن کاملThe Smc5-Smc6 DNA repair complex. bridging of the Smc5-Smc6 heads by the KLEISIN, Nse4, and non-Kleisin subunits.
Structural maintenance of chromosomes (SMC) proteins play fundamental roles in many aspects of chromosome organization and dynamics. The SMC complexes form unique structures with long coiled-coil arms folded at a hinge domain, so that the globular N- and C-terminal domains are brought together to form a "head." Within the Smc5-Smc6 complex, we previously identified two subcomplexes containing S...
متن کاملMeiotic DNA joint molecule resolution depends on Nse5–Nse6 of the Smc5–Smc6 holocomplex
Faithful chromosome segregation in meiosis is crucial to form viable, healthy offspring and in most species, it requires programmed recombination between homologous chromosomes. In fission yeast, meiotic recombination is initiated by Rec12 (Spo11 homolog) and generates single Holliday junction (HJ) intermediates, which are resolved by the Mus81-Eme1 endonuclease to generate crossovers and there...
متن کاملThe study of dose gamma rays of 192Ir source on DNA single strand break (SSB) and DNA double strand break (DSB) in soft tissue phantom
Introduction: Passage of ionizing radiation through the organs of living creatures develops clusters of damaged nucleotides inside the DNA rounds. 192Ir Gamma source is one of the most widely used sources in brachytherapy of cervical and prostate cancer. Thus, in this research, we investigated the flux of photons and its resulting secondary electrons, the single-strand break (S...
متن کاملSingle strand DNA binding of simian virus 40 tumor antigen.
Simian virus 40 T antigen binds to both single and double strand DNA. The single and double strand DNA binding activity of crude T antigen preparations was evaluated by chromatography of the antigen on DNA-cellulose columns. Crude T antigen was retained on both native and denatured DNA-cellulos columns and was eluted from both columns under similar conditions. The interaction of highly purified...
