CC -!- FUNCTION: Binds to the promoter regions of RNA polymerase II and III
CC small-nuclear RNA genes, type 3 RNA polymerase III non-coding RNA
CC genes, small nucleolar RNAs and transfer RNA genes. Required for
CC expression of mature 21U-RNAs. {ECO:0000269|PubMed:25373775}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00625,
CC ECO:0000269|PubMed:25373775}. Note=Diffuse nuclear localization.
CC Concentrated in foci within nuclei of proliferating and pachytene germ
CC cells. Foci localization is dependent on prde-1 activity.

CC IsoId=P91868-2; Sequence=VSP_057656;
CC -!- TISSUE SPECIFICITY: Broadly expressed in all tissues, including head,
CC vulva and tail. {ECO:0000269|PubMed:25373775}.
CC -!- DEVELOPMENTAL STAGE: Expressed throughout development.
CC {ECO:0000269|PubMed:25373775}.
CC -!- DISRUPTION PHENOTYPE: RNAi-mediated knockdown from larval stage L1
CC results in decreased 21U-RNA expression and disrupted distribution of
CC prde-1 foci within the nuclei of germ cells.
