Probable serine/threonine-protein kinase which may act in the sphingolipid-mediated signaling pathway (PubMed:22339665). May act downstream of TORC2 (TOR complex 2) and PDK1 to regulate sphingolipid metabolism (PubMed:22339665). ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-[protein] ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-threonyl-[protein] Decreases virulence in a mouse systemic infection model (PubMed:22339665). Sensitive to: high temperature; sirolimus; fluconazole; myriocin (phytosphingosine biosynthesis inhibitor); aureobasidin A (inositol-containing sphingolipid biosynthesis inhibitor); phytosphingosine (PubMed:22339665). Abnormal sphingolipid metabolism (PubMed:22339665). Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. RAC subfamily.
