Recombinant Human SUB1 Homolog(S. cerevisiae), His-tagged

Cat. No.: SUB1-2499H
Product Overview: Recombinant human SUB1 protein, fused to His-tag at N-terminus, was expressed inE.coliand purified by using conventional chromatography techniques. MW = 16.5 kDa (147aa).
Description: SUB1, also known as PC4, is a general coactivator that functions cooperatively with TAFs and mediates functional interactions between upstream activators and the general transcriptional machinery. SUB1 interacts with the activation domain of transcription factor IIA (TFIIA) and TATA-binding protein (TBP)-associated factors (TAFs) to directly bind to double stranded DNA. This protein induces both activation and repression of RNAPII basal transcription, depending on the presence or absence of these transcription factors and holoenzyme components.
Source: E.coli.
Form: Liquid. In 20 mM Tris-HCl buffer (pH8.0) containing 0.2M NaCl, 5mM DTT, 20% glycerol.
Purity: > 90% by SDS – PAGE.
Concentration: 0.5 mg/ml (determined by Bradford assay).
