This family consists of several DNA-directed RNA polymerase III polypeptides which are related to the Saccharomyces cerevisiae RPC82 protein. RNA polymerase C (III) promotes the transcription of tRNA and 5S RNA genes. In Saccharomyces cerevisiae, the enzyme is composed of 15 subunits, ranging from 160 to about 10 kDa [1]. This region is a probably DNA-binding helix-turn-helix.	Domain

This domain is found in the subunit RPC3 (also known as RPC62) of the eukaryotic DNA-directed RNA polymerase III, which synthesises small RNAs, such as 5S rRNA and tRNAs. RPC3 shows four defined domains folded around a fifth C-terminal domain consisting of two long alpha- helices (this entry). This domain appears to be reminiscent of coiled- coil motifs [1].	Domain
