RNA polymerase III (C) and its transcription factors.
Transcription of small genes by RNA polymerase III or C (pol III) involves many of the strategies that are used for transcription complex formation and occasionally the same components as those used by RNA polymerase II or B (pol II). Transcription complex formation is a multistep process that leads to the binding of a single initiation factor, TFIIIB, which in turn directs the selection of pol III. The general transcription factor TFIID can be involved in both pol II and pol III transcription. These and other similarities point towards a unifying mechanism for eukaryotic transcription initiation.
