"Interestingly, it has been reported that the serum and glucocorticoid inducible kinase 3 (SGK3) up-regulates I hERG1 by increasing protein levels in the plasma membrane, without affecting the K + chan[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"(Figure 2)In SGK3 and potassium transport, SGK3 can participate in up-regulating the activities of Kir2.1, Kir2.2, hERG, Kv7.1, BKCa, and Na /K - ATPase or indirectly enhance the potassium current induced by KCNA5 and Kv1.3 through the phosphorylation of Nedd4-2, participating in cardiac action potential, provide power for cardiac contraction, participate in renal proximal tubular membrane potential, maintain renal proximal tubular reabsorption function, and regulate neuronal excitability (Table 2)."

reach
"SGK3 could up-regulate the activity and abundance of hERG and change the duration of cardiac action potential."

reach
"HERG channel activity is up-regulated by the serum- and glucocorticoid inducible kinase isoforms SGK1 and SGK3."
