Background: The SGK family belongs to the AGC class of kinases and consists of three members; SGK1, SGK2 and SGK3. While SGK1 and SGK3 are ubiquitously expressed in all tissues, SGK2 is primarily expressed only in liver, kidney, and pancreas. SGK expression is rapidly induced by serum and glucocorticoid. All serum/glucocorticoid-regulated kinases are activated by insulin and growth factors via phosphatidylinositol 3-kinase and the 3-phosphoinositide-dependent kinase PDK1 and shows an extensive sequence homology to Akt in the kinase domain. In contrast to SGK1 and SGK2, SGK3 contains an extra Phox homology domain that also binds PIP3 and is required for its activation and endosomal localization. SGK3 regulates several transporters, ion channels and the Na+/K+ ATPase (e.g. the voltage gated K+ channel KCNA5) and plays an important role in breast cancer metastasis by phosphorylating the E3 ubiqutin ligase AIP4 and thereby promoting the degradation of the chemokine receptor CXCR4. Furthermore, SGK3 can phosphorylate Flightless-I, a coactivator of nuclear receptors including estrogen receptor (ER) and enhance ER transactivaction.
