Specification

• Species: Human
• Source: Sf9 Cells
• Tag: GST
• Protein Length: 3-487 a.a.
• Description: The protein encoded by this gene is a cytoplasmic kinase that is structurally similar to the yeast Ste20p kinase, which acts upstream of the stress-induced mitogen-activated protein kinase cascade. The encoded protein can phosphorylate myelin basic protein and undergoes autophosphorylation. A caspase-cleaved fragment of the encoded protein has been shown to be capable of phosphorylating histone H2B. The particular phosphorylation catalyzed by this protein has been correlated with apoptosis, and it"s possible that this protein induces the chromatin condensation observed in this process.
• Purification: GST-Affinity Chromatography.
• Product Identity: MST1 was confirmed as MST1 by mass spectroscopy LC-ESI-MS/MS.
• Storage Buffer: 50 mM HEPES pH 7.5, 100 mM NaCl, 5 mM DTT, 4 mM reduced glutathione, 20% glycerol.
