• Tag: C-Myc/DDK
• Predicted MW: 61.8 kDa
• Concentration: >50 ug/mL as determined by microplate BCA method
• Purity: > 80% as determined by SDS-PAGE and Coomassie blue staining
• Buffer: 25 mM Tris.HCl, pH 7.3, 100 mM glycine, 10% glycerol
• Bioactivity: SRPK3 activity verified in a biochemical assay: SRPK3 (SRSF protein kinase 3) (TP315496) activity was measured in a homogeneous time-resolved fluorescent (HTRF®) assay. SRPK3 is a serine/threonine kinase similar to a protein kinase which is specific for the SR (serine/arginine-rich domain) family of splicing factors. Varying concentrations of SRPK3 were added to a reaction mix containing ATP and a biotinylated kinase substrate and the reaction mixture was incubated to allow the protein to phosphorylate the substrate. HTRF detection reagents were then added, and the time-resolved fluorescent signal was measured on a Flexstation 3 microplate reader. The time resolved fluorescent signal is expressed as “delta R” or “ΔR” and is a ratio calculated from the fluorescent emission intensities of the donor and acceptor fluors.
• Preparation: Recombinant protein was captured through anti-DDK affinity column followed by conventional chromatography steps.
• Storage: Store at -80°C.
• Stability: Stable for 12 months from the date of receipt of the product under proper storage and handling conditions. Avoid repeated freeze-thaw cycles.

• Summary: This gene encodes a protein kinase similar to a protein kinase which is specific for the SR (serine/arginine-rich domain) family of splicing factors. A highly similar protein has been shown to play a role in muscle development in mice. Multiple transcript variants encoding different isoforms have been found for this gene.
