S. Cabantous et al., "Protein tagging and detection with engineered self-assembling fragments of green fluorescent protein," Nat Biotechnol, 23:102–7, Jan. 5, 2005.

A split [green fluorescent] protein-tagging and detection system was developed that can be easily used in high-throughput screens to obtain soluble, well-folded (recombinant) proteins. Additionally, the system holds great promise for the analysis of protein trafficking/protein localization (e.g., in eukaryotic cells) and for time-resolved monitoring of promoter coexpression.

S. Takyar et al., "mRNA helicase activity of the ribosome," Cell, 120:49–58, Jan. 14, 2005.

Using total ribosome reconstitution, stepwise in vitro translation, and primer extension assays, the authors demonstrate that the helicase activity that accomplishes the crucial function of unwinding double-stranded mRNA resides within the downstream tunnel of the ribosome itself. Molecular...
