Regulation and functions of bacterial PNPase.
Milano, Italy. In Wiley Interdiscip Rev Rna, Feb 2016
UNASSIGNED: Polynucleotide phosphorylase (PNPase) is an exoribonuclease that catalyzes the processive phosphorolytic degradation of RNA from the 3'-end.
An intriguing RNA species-perspectives of circularized RNA.
Shanghai, China. In Protein Cell, Dec 2015
CircRNAs have a more stable molecular structure that can resist to exoribonuclease comparing to those linear ones, and their molecular functions include microRNA sponge, regulatory roles in transcription, mRNA traps that compete with linear splicing, templates for translation and possibly other presently unknown roles.
Surprises in the 3'-end: 'U' can decide too!
Lisbon, Portugal. In Febs J, Sep 2015
Namely, Dis3L2 is a 3'-5' exoribonuclease from the RNase II/RNB family that has been shown to act preferentially on oligo(U)-tailed transcripts.
