CC -!- FUNCTION: Probable chromatin remodeling factor. Required for the
CC initial establishment of DNA methylation and for accumulation of 24-nt
CC siRNAs. May act on RNA templates by remodeling ribonucleoprotein
CC structures and thereby influencing the availability of the RNA to
CC polymerases. {ECO:0000269|PubMed:17526749,
CC ECO:0000269|PubMed:21150311}.
CC -!- SUBUNIT: Interacts with NRPD1, NRPD3 and SHH1.
CC {ECO:0000269|PubMed:21811420, ECO:0000269|PubMed:23637343}.
CC -!- SUBCELLULAR LOCATION: Nucleus, nucleoplasm
CC {ECO:0000269|PubMed:17526749}. Nucleus, nucleolus
CC {ECO:0000269|PubMed:17526749}. Note=In the nucleolus, localized in a
CC ring around the inner periphery.
CC -!- DISRUPTION PHENOTYPE: Decreased, but not completely blocked de novo
CC methylation. Probably due to a partial redundancy with CLSY2.
CC {ECO:0000269|PubMed:21150311}.
CC -!- MISCELLANEOUS: Associates in vivo with Pol IV but not with Pol V.
CC {ECO:0000305|PubMed:23637343}.
CC -!- SIMILARITY: Belongs to the helicase family. {ECO:0000305}.
