Here we report on a 3.0 Å crystal structure of a ternary complex of wild-type Thermus
thermophilus argonaute bound to a 5′-phosphorylated 21-nucleotide guide DNA and a 20-…

The laboratory mouse shares the majority of its protein-coding genes with humans, making
it the premier model organism in biomedical research, yet the two mammals differ in …

Eukaryotic chromosomes replicate in a temporal order known as the replication-timing
program 1 . In mammals, replication timing is cell-type-specific with at least half the genome …

The slicer activity of the RNA-induced silencing complex is associated with argonaute, the
RNase H-like PIWI domain of which catalyses guide-strand-mediated sequence-specific …
