General annotation (Comments)

Function	DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest core component of RNA polymerase III which synthesizes small RNAs, such as 5S rRNA and tRNAs. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. Pol III is composed of mobile elements and RPC2 is part of the core element with the central large cleft and probably a clamp element that moves to open and close the cleft By similarity.
Catalytic activity	Nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1).
Subunit structure	Component of the RNA polymerase III (Pol III) complex consisting of 17 subunits.
Subcellular location	Nucleus. Ref.4
Miscellaneous	Present with 1950 molecules/cell in log phase SD medium. Ref.5
Sequence similarities	Belongs to the RNA polymerase beta chain family.
