CC   -!- FUNCTION: DNA-dependent RNA polymerases catalyze the transcription of
CC       DNA into RNA using the four ribonucleoside triphosphates as substrates.
CC       Common component of RNA polymerases I, II and III which synthesize
CC       ribosomal RNA precursors, mRNA precursors and many functional non-
CC       coding RNAs, and small RNAs, such as 5S rRNA and tRNAs, respectively.
CC       Pol II is the central component of the basal RNA polymerase II
CC       transcription machinery. Pols are composed of mobile elements that move
CC       relative to each other. In Pol II, RPB6 is part of the clamp element
CC       and together with parts of RPB1 and RPB2 forms a pocket to which the
CC       RPB4-RPB7 subcomplex binds (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of the RNA polymerase I (Pol I), RNA polymerase II
CC       (Pol II) and RNA polymerase III (Pol III) complexes consisting of at
CC       least 13, 12 and 17 subunits, respectively.
CC       {ECO:0000250|UniProtKB:Q17684}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q17684}.
CC   -!- SIMILARITY: Belongs to the archaeal Rpo6/eukaryotic RPB6 RNA polymerase
CC       subunit family. {ECO:0000305}.
