Exchange reactions of poly(arylene ether ketone) dithioketals with aliphatic diols: formation and deprotection of poly(arylene ether ketal)s [PDF]

open access: yes, 2017
The dithioketal derivatives of industrially important, semi-crystalline poly(arylene ether ketone)s undergo facile exchange with aliphatic diols in the presence of N-bromo-succinimide to give a range of novel poly(arylene ether ketal)s.

RNA-binding proteins distinguish between similar sequence motifs to promote targeted deadenylation by Ccr4-Not

open access: yeseLife, 2019
The Ccr4-Not complex removes mRNA poly(A) tails to regulate eukaryotic mRNA stability and translation. RNA-binding proteins contribute to specificity by interacting with both Ccr4-Not and target mRNAs, but this is not fully understood.

Hemocompatibility poly (lactic acid) nanostructures: A bird’s eye view [PDF]

open access: yesNanomedicine Journal, 2020
The usage of clinical devices in the cardiovascular treatment, hemodialyze system and other biomedical applications has improved recently. Direct contacts of biomaterials like poly(lactic acid) biopolymer with blood result in the activating of platelets,

Segmented poly(A) tails significantly reduce recombination of plasmid DNA without affecting mRNA translation efficiency or half-life

open access: yesRNA: A publication of the RNA Society, 2019
Extensive research in the past decade has brought mRNA closer to the clinical realization of its therapeutic potential. One common structural feature for all cellular messenger RNAs is a poly(A) tail, which can either be brought in cotranscriptionally ...

A Raman spectroscopic study of the interaction between nucleotides and the DNA binding protein gp32 of bacteriophage T4 [PDF]

open access: yes, 1987
Raman spectra of the bacteriophage T4 denaturing protein gp32, its complex with the polynucleotides poly(rA), poly(dA), poly(dT), poly(rU), and poly(rC), and with the oligonucleotides (dA)8 and (dA)2, were recorded and interpreted.

Preparation and Properties of an Analogue of Poly(A) and Poly(G): Poly(isoguanylic acid) [PDF]

open access: yesEuropean Journal of Biochemistry, 1976
Isoguanosine-5'-pyrosphosphate, in the presence of an oligonucleotide primer, was polymerized by Escherichia coli polynucleotide phosphorylase under conditions analogous to those required for polymerization of 5'-GMP. The resulting poly(isoguanylic acid), poly(isoG), was a multistranded helix with a stability considerably higher than that of poly(G ...

Short Poly(A) Tails are a Conserved Feature of Highly Expressed Genes

open access: yesNature Structural & Molecular Biology, 2017
Poly(A) tails are important elements in mRNA translation and stability, although recent genome-wide studies have concluded that poly(A) tail length is generally not associated with translational efficiency in nonembryonic cells.

K-theory of virtually poly-surface groups [PDF]

open access: yes, 2002
In this paper we generalize the notion of strongly poly-free group to a larger class of groups, we call them strongly poly-surface groups and prove that the Fibered Isomorphism Conjecture of Farrell and Jones corresponding to the stable topological ...

Sequence specific binding of beta carboline alkaloid harmalol with deoxyribonucleotides: binding heterogeneity, conformational, thermodynamic and cytotoxic aspects. [PDF]

open access: yesPLoS ONE, 2014
Base dependent binding of the cytotoxic alkaloid harmalol to four synthetic polynucleotides, poly(dA).poly(dT), poly(dA-dT).poly(dA-dT), poly(dG).poly(dC) and poly(dG-dC).poly(dG-dC) was examined by various photophysical and calorimetric studies, and ...

The intrinsic structure of poly(A) RNA determines the specificity of Pan2 and Caf1 deadenylases

open access: yesNature Structural & Molecular Biology, 2019
The 3′ poly(A) tail of messenger RNA is fundamental to regulating eukaryotic gene expression. Shortening of the poly(A) tail, termed deadenylation, reduces transcript stability and inhibits translation.
