Cinderella factors have a ball
Article Abstract:
Protein synthesis in eukaryotes is thought to start when the ribosome binds to the 5' cap of the messenger RNA and proceeds along it, beginning translation at the first available ATG codon. However, it is not known how such scanning occurs. A new study provides a novel way of examining the early stages of the initiation process and maps the resulting complexes on mRNAs. For scanning to take place, two new eukaryotic initiation factors, eIF1 and eIF2, are needed, as well as the previously known eIFs 2, 3, 4A, 4B and 4F.

Long view from a high plateau
Article Abstract:
Many R proteins have leucine-rich repeats (LRRs) and the solvent-exposed surfaces of the repeats are subject to diversifying selection. It is indicated that unequal recombination events can have an effect on the evolution of a particular stretch of DNA, but contribute little to diversification.
