Serine/arginine-rich splicing factor 1 (SFRS1) belongs to the arginine/serine-rich splicing factor protein family, and functions in both constitutive and alternative pre-mRNA splicing. SFRS1 binds to pre-mRNA transcripts and components of the spliceosome, and can either initiate or inhibit splicing depending on the position of the pre-mRNA . The ability of SFRS1 to activate splicing is controlled by phosphorylation and interactions with other splicing factor associated proteins.
SRSF1 Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 254 amino acids (1-248) and having a molecular mass of 28.5kDa (Molecular size on SDS-PAGE will appear at approximately 28-40kDa).
SRSF1 is fused to 6 amino acid His-Tag at C-terminus and purified by proprietary chromatographic techniques.
Sterile Filtered colorless solution.
SRSF1 protein solution (0.25mg/ml) containing 20mM Tris-HCl buffer (pH 8.0), 100mM KCl, 1mM DTT, 0.2mM EDTA and 40% Glycerol.
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Greater than 95.0% as determined by SDS-PAGE.
