Serine/threonine protein kinases are important regulators of diverse cellular processes including metabolism, proliferation, and differentiation. We have previously identified the cDNA for a 49-kDa serine/threonine kinase, designated sgk, which is transcriptionally responsive to glucocorticoid hormones and serum in epithelial cells. We report here that sgk expression is also rapidly induced by dexamethasone or serum in Rat2 fibroblasts. Nuclear run-on and Northern blot analysis revealed that the induction of sgk mRNA is an immediate-early transcriptional response to serum stimulation of quiescent fibroblasts, which occurs just after the peak in c-jun transcription. In contrast to the glucocorticoid-stimulated sgk expression in Rat2 fibroblasts, the transcriptional induction of sgk by serum was transient and sgk transcripts decayed with a particularly rapid half-life of 20 min. The rapid turnover of sgk, in combination with its immediate-early transcriptional response to serum, suggests a novel mechanism for responding to mitogenic signals during G0 to S transition and entry into the cell cycle.
