CC -!- FUNCTION: Dicer-like endonuclease involved in cleaving double-stranded
CC RNA in the RNA interference (RNAi) pathway. Produces 21 to 25 bp dsRNAs
CC (siRNAs) which target the selective destruction of homologous RNAs
CC leading to sequence-specific suppression of gene expression, called
CC post-transcriptional gene silencing (PTGS). Part of a broad host
CC defense response against viral infection and transposons (By
CC similarity). {ECO:0000250}.
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250};
CC -!- SIMILARITY: Belongs to the helicase family. Dicer subfamily.
CC {ECO:0000255|PROSITE-ProRule:PRU00657}.
