RPB7 Rpb7p

Rpb7, hsRPB7, Rpb7p
This gene encodes the seventh largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. The protein functions in transcription initiation, and is also thought to help stabilize transcribing polyermase molecules during elongation. [provided by RefSeq, Jan 2009] (from NCBI)
