Unit Definition Intracellular poly(dA:dT) is detected by several cytosolic DNA sensors (CDS), such as cGAS, DAI, DDX41, IFI16 and LRRFIP1, triggering the production of type I interferons (IFNs) 1-3 . Poly(dA:dT) has been used to study RNA polymerase III–mediated promoter-independent transcription 38,39,40. Poly dA-dT. Polydeoxyribonucleotides made up of deoxyadenine nucleotides and thymine nucleotides. Present in DNA preparations isolated from crab species. Synthetic preparations have been used extensively in the study of DNA. Poly(dA:dT), a ubiquitous promoter element that stimulates transcription via its intrinsic DNA structure. The structure of poly(dA).poly(dT) currently arouses great interest, mainly because dAn.dTn stretches are associated with considerable DNA bending.

Synthetic preparations have been used extensively in the study of DNA. Poly(dA:dT) sequences are fragile because long single-strand poly(dA) stretches at the replication fork are unprotected by the replication protein A (RPA). We propose that the evolutionary expansion of poly(dA:dT) tracts in eukaryotic genomes promotes replication initiation, but at the cost of chromosome fragility. Any good anagrams for poly da-dt?

All (five) possible nucleosome configurations are illustrated, in which a nucleosome (cyan ovals) can be placed within five basepairs of the boundary (blue triangle). The results demonstrated that poly(dA:dT) triggered apoptosis instead of pyroptosis in melanocytes.

Jun 01, 1995 · Alexeev DG, Lipanov AA, Skuratovskii IYa Poly(dA).poly(dT) is a B-type double helix with a distinctively narrow minor groove. Nature. 325 (6107):821–823. [Bracco L, Kotlarz D, Kolb A, Diekmann S, Buc H. Synthetic curved DNA sequences can act as transcriptional activators in Escherichia coli.

Phased A-tracts contain short poly(dA:dT) tracts spaced by non-A-tract DNAs such that the poly(dA:dT) tracts are in phase with the helical period of Feb 01, 1987 For poly-(dA)·poly(dT) we find ∆V = +97 mL/mol of bound netropsin at pH 7.0 and 10 mM sodium phosphate buffer. For poly[d(AT)]·poly[d(AT)] we find ∆V = −16 mL/mol of bound netrospin. This striking differential effect suggests that the poly(dA)·poly(dT) duplex compresses more water (or is more extensively hydrated). May 21, 2012 Full Text RIG-I-dependent sensing of poly(dA:dT) through the induction of an RNA polymerase III-transcribed RNA intermediate. by Hornung, Veit and Hartmann, Gunther and Ablasser, Andrea and Bauernfeind, Franz and Latz, Eicke and Fitzgerald, Katherine A.
