Serum/Glucocorticoid Regulated Kinase 1 (SGK1) Human Recombinant Protein

This gene encodes a serine/threonine protein kinase that plays an important role in cellular stress response. This kinase activates certain potassium, sodium, and chloride channels, suggesting an involvement in the regulation of processes such as cell survival, neuronal excitability, and renal sodium excretion. High levels of expression of this gene may contribute to conditions such as hypertension and diabetic nephropathy. Several alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Jan 2009]

SGK1: serum and glucocorticoid-inducible kinase is an AGC protein kinase of the SGK family. Rapidly induced in response to a variety of stimuli including serum, glucocorticoids, follicle stimulating hormone, osmotic shock and mineralocorticoids. Can be activated via PI3K-dependent and -independent pathways. Plays a role in activating certain potassium, sodium and chloride channels, suggesting an involvement in the regulation of processes such as cell survival, neuronal excitability and renal sodium excretion. SGK is negatively regulated by ubiquitin modification and proteasome degradation.
