Introduction
Serum-and glucocorticoid-regulated kinase 1 (SGK1), a member of the "AGC" subfamily of serine/threonine protein kinases (which includes protein kinases A, G, and C), plays a crucial role in activating potassium, sodium, and chloride channels. This suggests its involvement in regulating cell survival, neuronal excitability, and renal sodium excretion. SGK1 is activated in vitro by 3-phosphoinositide-dependent protein kinase-1 (PDK-1) and in vivo by signals that activate phosphatidylinositol (PI) 3-kinase.
Description
Recombinant human SGK1, produced in E. coli, is a non-glycosylated polypeptide chain consisting of 393 amino acids (residues 60-431). With a molecular mass of 44.5 kDa, this protein is fused to a 21 amino acid His-tag at its N-terminus and purified using proprietary chromatographic techniques.
Physical Appearance
A clear, colorless solution that has been sterilized by filtration.
Formulation
The SGK1 protein solution (0.25 mg/mL) is supplied in a buffer containing 20 mM Tris-HCl (pH 8.0), 30% glycerol, 0.2 M NaCl, 2 mM DTT, and 0.1 mM PMSF.
Stability
For short-term storage (2-4 weeks), the product can be stored at 4°C. For long-term storage, it is recommended to freeze the product at -20°C. Adding a carrier protein (0.1% HSA or BSA) is advised for extended storage. Avoid repeated freeze-thaw cycles.
Purity
The purity of the SGK1 protein is greater than 90% as determined by SDS-PAGE analysis.
Synonyms
Serine/threonine-protein kinase Sgk1, Serum/glucocorticoid-regulated kinase 1, SGK1, SGK.
