SGK3: a novel regulator of renal phosphate transport?

ABSTRACT

Phosphate is a key constituent of several important molecules, and hyperphospatemia has been associated with increased cardiovascular mortality. The kidney plays a crucial role in phosphate metabolism, as it is able to modulate phosphate excretion. Serum- and glucocorticoid-inducible kinase 3 (SGK3) has been shown to regulate a wide variety of transport systems. Bhandaru et al. suggest that SGK3 may have a significant role in the regulation of renal tubular phosphate transport.
