DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Specific peripheric component of RNA polymerase III which synthesizes small RNAs, such as 5S rRNA and tRNAs. Component of the RNA polymerase III (Pol III) complex. Belongs to the eukaryotic RPC9 RNA polymerase subunit family.
