Application

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.

Preparation Note

Prepared from UDP using polynucleotide phosphorylase.

Plant pathogenic bacteria utilize an array of effector proteins to cause disease. Among them, transcriptional activator-like (TAL) effectors are unusual in the sense that they modulate transcription in the host. Although target genes and DNA specificity of TAL effectors have

Recent research hints at an underappreciated complexity in pre-miRNA processing and regulation. Global profiling of pre-miRNA and its potential to increase understanding of the pre-miRNA landscape is impeded by overlap with highly expressed classes of other non coding (nc) RNA.

De novo emergence demands a transition from disordered polypeptides into structured proteins with well-defined functions. However, can polypeptides confer functions of evolutionary relevance, and how might such polypeptides evolve into modern proteins? The earliest proteins present an even greater challenge

Major bacterial small RNAs (sRNAs) regulate the translation and stability of target mRNAs through base pairing with the help of the RNA chaperone Hfq. The Hfq-dependent sRNAs consist of three basic elements, mRNA base-pairing region, Hfq-binding site, and rho-independent terminator.
