UniProt functional annotation for P52657

UniProt code: P52657.

Organism: Homo sapiens (Human).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.
 
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}.
 
Subunit: TFIIA is a heterodimer of the large unprocessed subunit 1 and a small subunit gamma (By similarity). It was originally believed to be a heterotrimer of an alpha (p35), a beta (p19) and a gamma subunit (p12) (By similarity). Interacts with NCOA6 general coactivator (PubMed:10567404). TFIIA forms a complex with TBP (PubMed:11030333). Interacts with HSF1 (via transactivation domain) (PubMed:11005381). {ECO:0000250|UniProtKB:P52656, ECO:0000269|PubMed:10567404, ECO:0000269|PubMed:11005381, ECO:0000269|PubMed:11030333}.
Subunit: (Microbial infection) Interacts with SV40 Large T antigen. {ECO:0000269|PubMed:9632777}.
Subcellular location: Nucleus.
Similarity: Belongs to the TFIIA subunit 2 family. {ECO:0000305}.
