Cat.No.
SPT15-826S
Species
Saccharomyces cerevisiae
Product Name
Recombinant Saccharomyces Cerevisiae SPT15 Protein (2-240 aa), His-tagged
Product Overview
Recombinant Saccharomyces Cerevisiae (strain ATCC 204508/S288c) SPT15 Protein (2-240 aa) is produced by E. coli expression system. This protein is fused with a 6xHis tag at the N-terminal. Protein Description: Full Length of Mature Protein.
Description
General transcription factor that functions at the core of the DNA-binding general transcription factor complex TFIID. Binding of TFIID to a promoter (with or without TATA element) is the initial step in preinitiation complex (PIC) formation. TFIID plays a key role in the regulation of gene expression by RNA polymerase II through different activities such as transcription activator interaction, core promoter recognition and selectivity, TFIIA and TFIIB interaction, chromatin modification (histone acetylation by TAF1), facilitation of DNA opening and initiation of transcription.
