General Transcription Factor IIA, 1 (GTF2A1) in a complex along with TBP mediates transcriptional activity. GTF2A1 is a part of the transcription machinery of RNA polymerase II and is also participates in transcriptional activation.
GTF2A1 Human Recombinant produced in E. coli is. a single polypeptide chain containing 297 amino acids (1-274) and having a molecular mass of 32.2kDa. GTF2A1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
| UniProt Protein Function: | GTF2A1: a general transcription factor that plays an important role in transcriptional activation. A component of the transcription machinery of RNA polymerase II. Phosphorylated by Taf(II) 250 on serines that regulate TBP binding. Interacts with TBP (the TATA-binding protein). Two isoforms, 42 kDa and 37 kDa, are produced by alternative initiation. |
| UniProt Protein Details: | Protein type:Transcription, coactivator/corepressor Chromosomal Location of Human Ortholog: 14q31.1 Cellular Component: cytoplasm; nucleoplasm; transcription factor TFIIA complex Molecular Function:DNA binding; protein binding; protein heterodimerization activity; TATA-binding protein binding; transcription coactivator activity; transcription factor binding Biological Process: RNA elongation from RNA polymerase II promoter; snRNA transcription from RNA polymerase II promoter; transcription from RNA polymerase II promoter; transcription initiation from RNA polymerase II promoter |
| NCBI Summary: | Accurate transcription initiation on TATA-containing class II genes involves the ordered assembly of RNA polymerase II (POLR2A; MIM 180660) and several general initiation factors (summarized by DeJong and Roeder, 1993 [PubMed 8224848]). One of these factors is TFIIA, which when purified from HeLa extracts consists of 35-, 19-, and 12-kD subunits.[supplied by OMIM, Jul 2010] |
