Poly da dt

First, poly(dA:dT) stimulates Gcn4-activated transcription in a manner that is length dependent and inversely related to intracellular Gcn4 levels. Second, Datin, the only known poly(dA:dT)-binding protein, behaves as a repressor through poly(dA:dT) sequences.

Poly(deoxyadenylic-thymid ylic) (Poly(dA-dT) • Poly(dA-dT))acid is a double-stranded alternating copolymer DNA model for conformational studies of DNA structure dynamics and drug interaction. Packaging 10, 25, 50 units in serum bottle Other Notes Double-stranded alternating copolymer. Unit Definition Poly(dA:dT), a ubiquitous promoter element that stimulates transcription via its intrinsic DNA structure. Many yeast promoters contain homopolymeric dA:dT sequences that affect nucleosome formation in vitro and are required for wild-type levels of transcription in vivo. Here, we show that poly(dA:dT) is a novel promoter element whose function Search results for poly(dA:dT) at Sigma-Aldrich.

First, poly(dA:dT) stimulates Gcn4‐activated transcription in a manner that is length dependent and inversely related to intracellular Gcn4 levels. Second, Datin, the only known poly(dA:dT)‐binding protein, behaves as a repressor through poly(dA:dT) sequences. CD and uv absorption data showed that high molecular weight poly(dA‐dT) · poly(dA‐dT), at 298 K, undergoes an acid‐induced transition from B‐double helix to random coil in NaCl solutions of different concentrations, ranging from 0.005 to 0.600M. Similarly, titration of the polynucleotide with a strong base causes duplex‐to‐single It was suggested that poly(dA).poly(dT) rich sequences in yeast Saccharomyces cerevisiae act as elements of constitutive promoters by exclusion of nucleosomes (Struhl, K. (1985).

Poly(dA)·Poly(dT) molecules up to 1000 base pairs (bp) have been synthesized using enzymatic reaction, and characterization by STM observation shows that

Reducing AIM2 expression by shRNA in THP-1 cells decreased NFR-mediated IL-1β secretion, similar to the phenotype observed with the known AIM2 activator poly(dA:dT) ( Fig. 7 A ).

It is a repetitive synthetic double-stranded DNA sequence of poly(dA-dT)•poly(dT-dA) and a synthetic analog of B-DNA. Poly (deoxyadenylic-thymid ylic) (Poly (dA-dT) • Poly (dA-dT))acid is a double-stranded alternating copolymer DNA model for conformational studies of DNA structure dynamics and drug interaction. Homopolymeric stretches of deoxyadenosine nucleotides (A's) on one strand of double-stranded DNA, referred to as poly (dA:dT) tracts or A-tracts, are overabundant in eukaryotic genomes. They have unusual structural, dynamic, and mechanical properties, and may resist sharp bending. First, poly(dA:dT) stimulates Gcn4-activated transcription in a manner that is length dependent and inversely related to intracellular Gcn4 levels. Second, Datin, the only known poly(dA:dT)-binding protein, behaves as a repressor through poly(dA:dT) sequences.

Polydeoxyribonucleotides made up of deoxyadenine nucleotides and thymine nucleotidesPresent in DNA preparations isolated from crab species. Synthetic preparations have been used extensively in the study of DNA. 1985), poly(dA:dT) tracts function in both orientations and longertracts are more stimulatory than shorter tracts. The stimulation of his3 transcription due to poly(dA:dT) ranges from a 3-fold increase for a 17 bptract to a 6-fold increase for a42 bp tract. The observation that poly(dA:dT) stimulates his3 tran-A Length of dA:dT(bp) 0 17 29 42 Mixtures of antigen and varying ly(dA-dT)rpoly(dA-dT), and (C) native poly(dA-dT). 125 M with a minor population eluting at 0.25 M buffer. These results reiterate the formation of interstrand photocrosslink between poly(dA-dT) and 8-MOP and indicate the presence of at least one crosslink in each molecule of poly(dA-dT)-8-MOP photoadduct.
