Protein attributes

Sequence length	365 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	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.
Subcellular location	Nucleus.
Tissue specificity	Ubiquitous.
Sequence similarities	Contains 9 C2H2-type zinc fingers.
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.
Sequence caution	The sequence BAA06988.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. The sequence BAA06988.1 differs from that shown. Reason: Frameshift at positions 319 and 330.
