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

POLR3C exhibits helicase activity [2]. Helicases are enzymes responsible for unwinding ...	This entry represents a C-terminal WH-like domain (WH4) found in the DNA-directed RNA polymerase III subunit RPC3 (POLR3C) from humans (also known as hRPC62) [1]. POLR3C exhibits helicase activity [2]. Helicases are enzymes responsible for unwinding DNA or RNA helices, facilitating essential processes such as transcription and DNA replication. RNA polymerase (pol) III is responsible for transcribing tRNAs, 5S RNA, and U6 RNA in eukaryotes. The human Pol III complex consists of a total of 17 subunits.	Domain
