Applicazioni

Polyuridylic acid (Poly(U)), a homopolymer of uridine, is used as a single-stranded RNA model compound often in comparison with other ssRNA model oligonucleotides such as Poly(I) and Poly(C) to study processes that are dependent upon ssRNA regulation such as Toll-like receptor regulation. Poly(U) is used as an effective agonist for TLR7.

Nota sulla preparazione

Prepared from UDP using polynucleotide phosphorylase.

The aggregation of the human tau protein into neurofibrillary tangles is directly diagnostic of many neurodegenerative conditions termed tauopathies. The species, factors and events that are responsible for the initiation and propagation of tau aggregation are not clearly established, even

Binding of two 9-O-(ω-amino) alkyl ether berberine analogs BC1 and BC2 to the RNA triplex poly(U)(•)poly(A)(*)poly(U) was studied by various biophysical techniques. Berberine analogs bind to the RNA triplex non-cooperatively. The affinity of binding was remarkably high by about 5

Although transcription and transcript processing in the chloroplasts of plants have been extensively characterised, the RNA metabolism of other chloroplast lineages across the eukaryotes remains poorly understood. In this paper, we use RT-PCR to study transcription and transcript processing in
