The function of the protein phosphatase Glc7p in transcription termination, RNA processing and transcriptional regulation of ribosomal protein genes [PDF]
Gene transcription in general can be subdivided into three main phases: transcription initiation, elongation and termination. The enzyme that accomplishes transcription of protein coding genes, snRNAs and snoRNAs is RNA polymerase II (RNAP II).

Intracellular RNA cleavage by the hairpin ribozyme [PDF]
Studies involving ribozyme-directed inactivation of targeted RNA molecules have met with mixed success, making clear the importance of methods to measure and optimize ribozyme activity within cells. The interpretation of biochemical assays for determining ribozyme activity in the cellular environment have been complicated by recent results indicating ...

RNA-specific ribonucleotidyl transferases [PDF]
RNA-specific nucleotidyl transferases (rNTrs) are a diverse family of template-independent polymerases that add ribonucleotides to the 3'-ends of RNA molecules.

A hepatitis C virus cis-acting replication element forms a long-range RNA-RNA interaction with upstream RNA sequences in NS5B [PDF]
The genome of hepatitis C virus (HCV) contains cis-acting replication elements (CREs) comprised of RNA stem-loop structures located in both the 5' and 3' non-coding regions (NCR), and in the NS5B coding sequence.

Diverging affinity of tospovirus RNA silencing suppressor proteins, NSs, for various RNA duplex molecules [PDF]
The tospovirus NSs protein was previously shown to suppress the antiviral RNA silencing mechanism in plants. Here the biochemical analysis of NSs proteins from different tospoviruses, using purified NSs or NSs containing cell extracts, is described.

Structure of the Complete RNA Polymerase II Elongation Complex and its Interaction with the Elongation Factor TFIIS [PDF]
This thesis describes crystal structures of complete, 12-subunit yeast RNA polymerase II (Pol II) in complex with a synthetic transcription bubble and product RNA, with an NTP substrate analogue, and in complex with the transcription elongation factor ...

Transcriptional termination enhances protein expression in human cells [PDF]
Transcriptional termination of mammalian RNA polymerase II (Pol II) requires a poly(A) (pA) signal and, often, a downstream terminator sequence. Termination is triggered following recognition of the pA signal by Pol II and subsequent pre-mRNA cleavage ...

Kinetics of Pre-mRNA 3’ End Cleavage [PDF]
3’ end cleavage and polyadenylation are required steps in pre-mRNA maturation. The rate at which 3’ end cleavage occurs can determine the temporal availability of mRNA for subsequent function throughout the cell and is likely tightly regulated.

Detection of genome-scale ordered RNA structure (GORS) in genomes of positive-stranded RNA viruses:Implications for virus evolution and host persistence [PDF]
Discrete RNA secondary and higher-order structures, typically local in extent, play a fundamental role in RNA virus replication. Using new bioinformatics analysis methods, we have identified genome-scale ordered RNA structure (GORS) in many genera and ...
