CC   -!- FUNCTION: Has a role in the RNA interference (RNAi) pathway which is
CC       important for heterochromatin formation and accurate chromosome
CC       segregation. A member of the RNA-directed RNA polymerase complex (RDRC)
CC       which is involved in the generation of small interfering RNAs (siRNAs)
CC       and mediate their association with the RNA-induced transcriptional
CC       silencing (RITS) complex. RITS acts as a priming complex for dsRNA
CC       synthesis at the site of non-coding centromeric RNA.
CC       {ECO:0000269|PubMed:15607976}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + RNA(n) = diphosphate + RNA(n)-3'-adenine ribonucleotide;
CC         Xref=Rhea:RHEA:11332, Rhea:RHEA-COMP:14527, Rhea:RHEA-COMP:17347,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:33019, ChEBI:CHEBI:140395,
CC         ChEBI:CHEBI:173115; EC=2.7.7.19;
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   -!- SUBUNIT: Cid12, hrr1 and rdp1 interact forming the RNA-directed RNA
CC       polymerase complex (RDRC). The RDRC complex interacts with the RITS
CC       complex via interaction between ago1 and hrr1. Clr4 has a role in
CC       mediating this interaction.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:16823372}. Nucleus
CC       {ECO:0000269|PubMed:15607976, ECO:0000269|PubMed:16823372}.
CC   -!- SIMILARITY: Belongs to the DNA polymerase type-B-like family.
CC       {ECO:0000305}.
