Functioni

Interacts with the internal control region (ICR) of approximately 50 bases within the 5S RNA genes, is required for correct transcription of these genes by RNA polymerase III. Also binds the transcribed 5S RNA's. May initiate transcription of the 5S ribosomal RNA gene and maintain the stability of transcription of other genes.

Caution

It is uncertain whether Met-1 is the initiator. Based on the lack of an in-frame AUG codon, mammalian TFIIIA may be translated from this non-AUG initiation site, which has a good Kozak context and which is well conserved among mammals.Curated
