products description :
Description: GTF2B Human Recombinant produced in E Coli is a single, non-glycosylated, polypeptide chain containing 336 amino acids (1-316 a.a.) and having a molecular mass of 36.9 kDa. The GTF2B is fused to a 20 amino acid His Tag at N-terminus and purified by proprietary chromatographic techniques. Introduction: GTF2B is one of the ubiquitous factors needed for transcription initiation by RNA polymerase II preinitiation factor. GTF2B localizes to the nucleus where it forms a complex (the DAB complex) with transcription factors IID and IIA. GTF2 plays a role as a bridge between IID, which initially recognizes the promoter sequence, and RNA polymerase II. GTF2B is involved in the selection of the transcription start site.

ncbi summary :
This gene encodes the general transcription factor IIB, one of the ubiquitous factors required for transcription initiation by RNA polymerase II. The protein localizes to the nucleus where it forms a complex (the DAB complex) with transcription factors IID and IIA. Transcription factor IIB serves as a bridge between IID, the factor which initially recognizes the promoter sequence, and RNA polymerase II. [provided by RefSeq, Jul 2008]
uniprot summary :
GTF2B: General factor that plays a major role in the activation of eukaryotic genes transcribed by RNA polymerase II. Associates with TFIID-IIA (DA complex) to form TFIID-IIA- IIB (DAB-complex) which is then recognized by polymerase II. Interacts with the transcription elongation factor TCEA2. Interacts with HIV-1 Vpr. Interacts with GPBP1. Interacts with Epstein-Barr virus EBNA2. Belongs to the TFIIB family. Protein type: Nuclear receptor co-regulator; Transcription factor; Acetyltransferase. Chromosomal Location of Human Ortholog: 1p22-p21. Cellular Component: nucleoplasm; nucleolus; nucleus. Molecular Function: protein binding; zinc ion binding; TATA-binding protein binding; thyroid hormone receptor binding; transcription factor binding. Biological Process: transcription from RNA polymerase II promoter; transcription initiation from RNA polymerase II promoter; viral reproduction; regulation of transcription, DNA-dependent; RNA elongation from RNA polymerase II promoter; gene expression
