Trim25 is an RNA-specific activator of Lin28a/TuT4-mediated uridylation [PDF]
SummaryRNA binding proteins have thousands of cellular RNA targets and often exhibit opposite or passive molecular functions. Lin28a is a conserved RNA binding protein involved in pluripotency and tumorigenesis that was previously shown to trigger TuT4 ...

Control of human adenovirus type 5 gene expression by cellular Daxx/ATRX chromatin-associated complexes [PDF]
Death domain–associated protein (Daxx) cooperates with X-linked α-thalassaemia retardation syndrome protein (ATRX), a putative member of the sucrose non-fermentable 2 family of ATP-dependent chromatin-remodelling proteins, acting as the core ATPase ...

Structure, Function and Regulation of the Hsp90 Machinery
Heat shock protein 90 (Hsp90) is an ATP-dependent molecular chaperone which is essential in eukaryotes. It is required for the activation and stabilization of a wide variety of client proteins and many of them are involved in important cellular pathways.

NAD+-dependent DNA ligases of Mycobacterium tuberculosis and Streptomyces coelicolor [PDF]
Sequencing of the genomes of Mycobacterium tuberculosis H37Rv and Streptomyces coelicolor A3(2) identified putative genes for an NAD+-dependent DNA ligase. We have cloned both open reading frames and overexpressed the protein products in Escherichia coli.

Large Phenotypic Enhancement of Structured Random RNA Pools. [PDF]
Laboratory evolution of functional RNAs has applications in many areas of chemical and synthetic biology. In vitro selections critically depend on the presence of functional molecules, such as aptamers and ribozymes, in the starting sequence pools.

A conformational RNA zipper promotes intron ejection during non-conventional XBP1 mRNA splicing. [PDF]
The kinase/endonuclease IRE1 is the most conserved signal transducer of the unfolded protein response (UPR), an intracellular signaling network that monitors and regulates the protein folding capacity of the endoplasmic reticulum (ER).

The 2'-5' RNA Ligase of Escherichia coli: Purification, Cloning, and Genomic Disruption [PDF]
An RNA ligase previously detected in extracts of Escherichia coli is capable of joining Saccharomyces cerevisiae tRNA splicing intermediates in the absence of ATP to form a 2-5 phosphodiester linkage (Greer, C., Javor, B., and Abelson, J. (1983) Cell 33,

Evaluation of NAD(+)-dependent DNA ligase of mycobacteria as a potential target for antibiotics [PDF]
Mycobacteria contain genes for several DNA ligases, including ligA, which encodes a NAD+-dependent enzyme that has been postulated to be a target for novel antibacterial compounds.
