Phosphorylation of GSK3 by PKB or SGK1 inhibits GSK3 activity|estern blotting using an antibody specific for the PKB/SGK1 consensus phosphorylation site in GSK3a/beta (serine 21 and 9 respectively) revealed an increase in GSK3a/beta phosphorylation in human embryonic kidney 293 (HEK293) cells overexpressing wild type SGK1, constitutively active SGK1, but not catalytically inactive SGK1.|The effect of SGK1 was mimicked by PKB and SGK3. |

Protein kinase SGK mediates survival signals by phosphorylating the forkhead transcription factor FKHRL1 (FOXO3a)|However, SGK and Akt display differences with respect to the efficacy with which they phosphorylate the three regulatory sites on FKHRL1. While both kinases can phosphorylate Thr-32, SGK displays a marked preference for Ser-315 whereas Akt favors Ser-253. These findings suggest that SGK and Akt may coordinately regulate the function of FKHRL1 by phosphorylating this transcription factor at distinct sites. The efficient phosphorylation of these three sites on FKHRL1 by SGK and Akt appears to be critical to the ability of growth factors to suppress FKHRL1-dependent transcription, thereby preventing FKHRL1 from inducing cell cycle arrest and apoptosis. |

Among the sites identified, only six were previously suggested to be the targets for specific kinases using in silico and/or in vitro analyses: S36 and S525 were attributed to the regulation by PKA; S484 and S664 were assigned to the serum- and glucocorticoid-inducible kinase 3 (SGK3); and S516 and S571 were ascribed to CaMKII (reviewed in Marionneau and Abriel, 2015). In marked contrast, several previously described phosphorylation sites were not detected in the present study, including the PKA-dependent S528, the CaMKII-associated T594, the PKC-dependent S1506, the adenosine monophosphate–activated protein kinase (AMPK)–dependent T101 (Liu et al., 2019), and the six Fyn-dependent tyrosines (Ahern et al., 2005; Iqbal et al., 2018).|The simplest interpretation of these findings is that these three phosphorylation clusters, at positions S457-S460, S483-T486, and S664-S671, are likely involved in regulating the basal and/or gating properties of native cardiac NaV1.5 channels. Conversely, the other phosphorylation sites, with lower stoichiometries, may play spatially or temporally distinct roles in the physiological or more pathophysiological regulation of channel expression or gating. | Remarkably, this MS analysis also revealed that the vast majority of identified phosphorylation sites (at least 26) are clustered, suggesting concomitant phosphorylation and roles in regulating channel expression and/or function. Unexpectedly, however, except for S664, S667, and S671, no apparent effects of phosphomimetic or phosphosilent mutations were observed on heterologously expressed (in HEK-293 cells) NaV1.5 |

One of the most studied events controlled by ptdins(3,4,5)p3, comprises the activation of a of agc family protein kinases, including isoforms of protein kinase b (pkb)/akt, p70 ribosomal s6 kinase (s6k), serum- and glucocorticoid-induced protein kinase (sgk) and protein kinase c (pkc), which play crucial roles in regulating physiological processes relevant to metabolism, growth, proliferation and survival. Here, we review recent biochemical, genetic and structural studies on the 3-phosphoinositide-dependent protein kinase-1 (pdk1), which phosphorylates and activates the agc kinase members regulated by pi 3-kinase. We also discuss whether inhibitors of pdk1 might have chemotherapeutic potential in the treatment of cancers in which the pdk1-regulated agc kinases are constitutively activated. |

A catalytic small molecule pan-SGK inhibitor, GSK650394 (Sherk et al., 2008) also significantly blocks MCF7, ZR-75-1, and T47D cell migration (Figure 5C, Figures S4B–C). Finally, ectopic expression of SGK3 also promotes invasive migration through Matrigel (Figure 5D). Therefore, SGK3 protein kinase activity promotes migration of breast cancer cells that display elevated levels of INPP4B. |
