Fig 9. Proposed mechanism by which Piwi mediates c-Fos repression.

Fig 9

Piwi protein and unknown associated factors are recruited by the c-Fos 3’UTR to bind the mRNA. The Piwi protein complex includes the 5’ and 3’ nucleases that generate the mature primary piRNAs. Processing of the c-Fos 3’UTR into mature piRNAs cause instability and degradation of the whole mRNA.
