>gnl|CDD|72942 cd04657, Piwi_ago-like, Piwi_ago-like: PIWI domain, Argonaute-like
subfamily. Argonaute is the central component of the
RNA-induced silencing complex (RISC) and related
complexes. The PIWI domain is the C-terminal portion of
Argonaute and consists of two subdomains, one of which
provides the 5' anchoring of the guide RNA and the
other, the catalytic site for slicing..

>gnl|CDD|145366 pfam02171, Piwi, Piwi domain. This domain is found in the protein
Piwi and its relatives. The function of this domain is
the dsRNA guided hydrolysis of ssRNA. Determination of
the crystal structure of Argonaute reveals that PIWI is
an RNase H domain, and identifies Argonaute as Slicer,
the enzyme that cleaves mRNA in the RNAi RISC complex.
In addition, Mg+2 dependence and production of 3'-OH and
5' phosphate products are shared characteristics of
RNaseH and RISC. The PIWI domain core has a tertiary
structure belonging to the RNase H family of enzymes.
RNase H fold proteins all have a five-stranded mixed
beta-sheet surrounded by helices. By analogy to RNase H
enzymes which cleave single-stranded RNA guided by the
DNA strand in an RNA/DNA hybrid, the PIWI domain can be
inferred to cleave single-stranded RNA, for example
mRNA, guided by double stranded siRNA.
