POLR3B: Proteins and Enzymes

RPC2 is the second largest subunit of the 17 subunits that make up RNA polymerase III. RNA polymerase III is responsible for the synthesis of small RNA components that are part of the machinery involved in pre-mRNA splicing, and tRNA processing. Alternative names for RPC2 include DNA-directed RNA polymerase III subunit RPC2, RNA polymerase III subunit C2, DNA-directed RNA polymerase III subunit B, DNA-directed RNA polymerase III 127.6 kDa polypeptide, C128, POLR3B, and FLJ10388.
