| Function: | |
TFIIA is a component of the transcription machinery of RNA polymerase II and plays an important role in transcriptional activation. TFIIA in a complex with TBP mediates transcriptional activity. {ECO:0000269|PubMed:11030333, ECO:0000269|PubMed:16537915}. |
|
||
| Subunit: | |
TFIIA is a heterodimer of the large unprocessed subunit 1 and a small subunit gamma. It was originally believed to be a heterotrimer of an alpha (p35), a beta (p19) and a gamma subunit (p12). TFIIA forms a complex with TBP. {ECO:0000269|PubMed:11030333}. |
| Subcellular location: | |
Nucleus. |
| Ptm: | |
The alpha and beta subunits are postranslationally produced from the precursor form by TASP1. The cleavage promotes proteasomal degradation. {ECO:0000269|PubMed:16537915}. |
| Similarity: | |
Belongs to the TFIIA subunit 1 family. {ECO:0000305}. |
