Regulation of protein synthesis is an important aspect of growth control. RNA polymerase (pol) III plays a key role in this process by catalysing production of tRNA and 5 S rRNA. Growth factors trigger a rapid increase in pol III activity and this is essential for cell proliferation. The transcription factor TFIIIB plays a key role in controlling pol III activity and is a target for regulation by a number of mechanisms. This review will focus on how TFIIIB is targeted by these proteins in response to mitogen stimulation.
