Protein Information (annotations from UniProt)

Database IDHIV0001233
UniProt IDQ9UKN8
Primary gene name(s)GTF3C4
Synonym gene name(s)unknown
Protein nameGeneral transcription factor 3C polypeptide 4
Protein functionEssential for RNA polymerase III to make a number of small nuclear and cytoplasmic RNAs, including 5S RNA, tRNA, and adenovirus-associated, VA RNA of both cellular and viral origin. Has histone acetyltransferase activity, HAT with unique specificity for free and nucleosomal H3. May cooperate with GTF3C5 in facilitating the recruitment of TFIIIB and RNA polymerase through direct interactions with BRF1, POLR3C and POLR3F. May be localized close to the A box.
Subcellular locationNucleus.
