Active Recombinant Human GTF2A1, P19, GST-tagged

• Cat.No.: GTF2A1-1172H

Specification

• Cat. No.: GTF2A1-1172H
• Description: The Transcription Factor IIA (TFIIA) has been shown to bind to the TBP-DNA complex and to increase the affinity of TBP for the TATA element. Human TFIIA consists of three subunits of 35 kDa (α-subunit), 19 kDa (β-subunit) and 12 kDa (γ-subunit). The α- and β-subunits are derived from the product, p55, of a single gene by an unknown mechanism. However, recombinant p55, in combination with a 12 kDa subunit (γ-subunit), retains native TFIIA activity. GST-TFIIA (p19) is isolated from anE. colistrain that carries the coding sequence of TFIIA -subunit under the control of a T7 promoter. GST-TFIIA (p19) has been applied in protein-protein interaction assays.
