CC   -!- FUNCTION: DNA-dependent RNA polymerase (RNAP) catalyzes the
CC       transcription of DNA into RNA using the four ribonucleoside
CC       triphosphates as substrates. This subunit is less well bound than the
CC       others. {ECO:0000255|HAMAP-Rule:MF_00864}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=a ribonucleoside 5'-triphosphate + RNA(n) = diphosphate +
CC         RNA(n+1); Xref=Rhea:RHEA:21248, Rhea:RHEA-COMP:14527, Rhea:RHEA-
CC         COMP:17342, ChEBI:CHEBI:33019, ChEBI:CHEBI:61557, ChEBI:CHEBI:140395;
CC         EC=2.7.7.6; Evidence={ECO:0000255|HAMAP-Rule:MF_00864};
CC   -!- SUBUNIT: Part of the 13-subunit RNA polymerase complex. Forms a stalk
CC       with Rpo7 that extends from the main structure.
CC       {ECO:0000269|PubMed:18235446}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00864}.
CC   -!- SIMILARITY: Belongs to the eukaryotic RPB4 RNA polymerase subunit
CC       family. {ECO:0000255|HAMAP-Rule:MF_00864}.
