ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-[protein] ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-threonyl-[protein] Interacts with mouse THEM4. The AGC-kinase C-terminal mediates interaction with THEM4. Autophosphorylated on threonine and serine residues. This protein is synthesized as a Gag-Akt polyprotein. Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. RAC subfamily.
