== Function ==

TFIIIB150 is a subunit of the TFIIIB transcription initiation complex, which recruits [RNA polymerase III](/source/RNA_polymerase_III) to target promoters in order to initiate transcription. The encoded protein localizes to concentrated aggregates in the nucleus, and is required for transcription from all three types of polymerase III promoters. It is phosphorylated by [casein kinase 2](/source/casein_kinase_2) during [mitosis](/source/mitosis), resulting in its release from [chromatin](/source/chromatin) and suppression of polymerase III transcription.<ref name="entrez" />
