Role of single-stranded DNA in targeting REV1 to primer termini.
Cellular functions of the REV1 gene have been conserved in evolution and appear important for maintaining genetic integrity through translesion DNA synthesis. This study documents a novel biochemical activity of human REV1 protein, due to higher affinity for single-stranded DNA (ssDNA) than the primer terminus. Preferential binding to long ssDNA regions of the template strand means that REV1 is...
متن کاملRegulation of single-stranded DNA binding by the C termini of Escherichia coli single-stranded DNA-binding (SSB) protein.
The homotetrameric Escherichia coli single-stranded DNA-binding (SSB) protein plays a central role in DNA replication, repair, and recombination. In addition to its essential activity of binding to transiently formed single-stranded (ss) DNA, SSB also binds an array of partner proteins and recruits them to their sites of action using its four intrinsically disordered C-terminal tails. Here we s...
متن کاملSingle primer-triggered isothermal amplification for double-stranded DNA detection.
Here we have devised a new generation of isothermal double-stranded DNA (dsDNA) detection method, termed single primer-triggered isothermal amplification (SAMP). It is very simple only requiring one primer and a few copies of dsDNA in less than an hour are detectable with multiple signal amplification steps.

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولDNA fragments with specific nucleotide sequences in their single-stranded termini exhibit unusual electrophoretic mobilities.
DNA restriction fragments, 120-650 base pairs (bp) in length, with 5'-GCGC-3', 5'-GGCC-3' or 3'-GCGC-5' single-stranded overhanging termini, give rise to diffuse bands of unusual electrophoretic mobility in non-denaturing polyacrylamide gels. This shift in electrophoretic mobility can be observed at 4-12 degreesC, not at higher temperatures, but is stabilized by 5-10 mM Mg2+, even at 37 degrees...
