Cleavage stimulation factor subunit 1 (CSTF1) is involved in the polyadenylation and 3'end cleavage of pre-mRNAs. The CSTF1 gene encodes one of three subunits which merge to produce cleavage stimulation factor (CSTF). Like the mammalian G protein beta subunits, CSTF1 contains transducin-like repeats. CSTF1 is one of the numerous factors necessary for polyadenylation and 3'-end cleavage of mammalian pre-mRNAs. CSTF1 is responsible for the interaction of CSTF with other factors to create a stable complex on the pre-mRNA.
CSTF1 Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 437 amino acids (1-431a.a.) and having a molecular mass of 49.1kDa (Molecular size on SDS-PAGE will appear at approximately 40-57kDa).
CSTF1 is expressed with a 6 amino acids His tag at C-Terminus and purified by proprietary chromatographic techniques.
CSTF1 protein solution (0.5mg/ml) contains Phosphate Buffered Saline (pH 7.4), 1mM DTT and 20% glycerol.
Greater than 90.0% as determined by SDS-PAGE.
