Polymerase (RNA) III (DNA directed) polypeptide H (22.9kD)
Gene Summary
POLR3H belongs to the eukaryotic RPB7/RPC8 RNA polymerase subunit family. DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. POLR3H is a specific peripheric component of RNA polymerase III which synthesizes small RNAs, such as 5S rRNA and tRNAs.
