Date: 2009-05-05 02:07 pm (UTC)"Piwi-interacting RNAs (piRNAs) silence transposons
in animal germ cells. piRNAs are thought to derive
from long transcripts spanning transposon-rich
genomic loci and to direct an autoamplification loop
in which an antisense piRNA, bound to Aubergine
or Piwi protein, triggers production of a sense piRNA
bound to the PIWI protein Argonaute3 (Ago3). In turn,
the new piRNA is envisioned to produce a second
antisense piRNA. Here, we describe strong loss-offunction
mutations in ago3, allowing a direct genetic
test of this model. We find that Ago3 acts to amplify
piRNA pools and to enforce on them an antisense
bias, increasing the number of piRNAs that can act
to silence transposons. We also detect a second,
Ago3-independent piRNA pathway centered on
Piwi. Transposons targeted by this second pathway
often reside in the flamenco locus, which is expressed
in somatic ovarian follicle cells, suggesting
a role for piRNAs beyond the germline."
