GTF3A - general transcription factor IIIA Gene
Also Known as AP2; TFIIIA
Species: Homo sapiens
About GTF3A
This gene has 8 transcripts (splice variants), 275 orthologues and 6 paralogues. Ubiquitous expression in fat (RPKM 54.8), heart (RPKM 50.8) and 25 other tissues.
Summary
The product of this gene is a Zinc Finger Protein with nine Cis[2]-His[2] zinc finger domains. It functions as an RNA polymerase III transcription factor to induce transcription of the 5S rRNA genes. The protein binds to a 50 bp internal promoter in the 5S genes called the internal control region (ICR), and nucleates formation of a stable preinitiation complex. This complex recruits the TFIIIC and TFIIIB transcription factors and RNA polymerase III to form the complete transcription complex. The protein is thought to be translated using a non-AUG translation initiation site in mammals based on sequence analysis, protein homology, and the size of the purified protein.
