Driven Polymer Translocation Through a Narrow Pore [PDF]
Motivated by experiments in which a polynucleotide is driven through a proteinaceous pore by an electric field, we study the diffusive motion of a polymer threaded through a narrow channel with which it may have strong interactions. We show that there is

Novel Aspects of Polynucleotide Phosphorylase Function in Streptomyces
Polynucleotide phosphorylase (PNPase) is a 3′–5′-exoribnuclease that is found in most bacteria and in some eukaryotic organelles. The enzyme plays a key role in RNA decay in these systems.

Emerging Diversity of Channelrhodopsins and Their Structure-Function Relationships
Cation and anion channelrhodopsins (CCRs and ACRs, respectively) from phototactic algae have become widely used as genetically encoded molecular tools to control cell membrane potential with light. Recent advances in polynucleotide sequencing, especially

Specific recognition of a multiply phosphorylated motif in the DNA repair scaffold XRCC1 by the FHA domain of human PNK. [PDF]
Short-patch repair of DNA single-strand breaks and gaps (SSB) is coordinated by XRCC1, a scaffold protein that recruits the DNA polymerase and DNA ligase required for filling and sealing the damaged strand.

An oligonucleotide labeling system was developed that can produce radiolabeled hybridization probes with tenfold or more higher specific activity than is obtained by traditional 5¢-end-labeling with polynucleotide kinase.

Small-molecule inhibitor leads of ribosome-inactivating proteins developed using the doorstop approach. [PDF]
Ribosome-inactivating proteins (RIPs) are toxic because they bind to 28S rRNA and depurinate a specific adenine residue from the α-sarcin/ricin loop (SRL), thereby inhibiting protein synthesis.

Micro-RNAS that control myosin expression and myofiber identity [PDF]
The present invention relates to the identification of two microRNAs, miR-499 and miR-208b, that repress fast skeletal muscle contractile protein genes. Expression of miR-499 and/or miR-208b can be used to repress fast fiber genes and activate slow fiber

Micro-RNA family that modulates fibrosis and uses thereof [PDF]
The present invention relates to the identification of a microRNA family, designated miR-29a-c, that is a key regulator of fibrosis in cardiac tissue. The inventors show that members of the miR-29 family are down-regulated in the heart tissue in response
