"These observations suggest that RET/PTC is able to phosphorylate the Y315 residue of PKB, an event that results in maximal activation of PKB for RET/PTC-induced thyroid tumorigenesis."

"Here we demonstrate that AKT is a direct substrate of PTK6 and that AKT tyrosine residues 315 and 326 are phosphorylated by PTK6."

"We also showed that phosphorylation of Tyr-315 in Akt induced by Src or EGF is dependent on the integrity of this proline-rich motif. Furthermore, the Akt mutant lacking this proline motif fails to block the transcription activity of Forkhead in 293 cells and poorly stimulates the proliferation of Madin-Darby canine kidney cells. Taken together, our data suggest that the interaction between the SH3 domain of Src family kinases and the proline-rich motif in the C-terminal regulatory region of Akt is required for tyrosine phosphorylation of Akt and its subsequent activation."

"The PKB Y315 residue, which is known to be phosphorylated by Src tyrosine kinase, was also a major site of phosphorylation by RET/PTC. RET/PTC-mediated tyrosine phosphorylation results in the activation of PKB kinase activity"

"Regulation of Akt/PKB Activation by Tyrosine PhosphorylationAs shown in Fig. 2 d, while mutation of Tyr340 has little effect on either tyrosine phosphorylation or kinase activity of Akt induced by Src527F, substitution of Tyr315 or Tyr326 with a phenylalanine, respectively, dramatically reduces both the tyrosine phosphorylation and kinase activity of Akt. The combination of these two mutations abolishes Src-induced tyrosine phosphorylation of Akt as well as its kinase activity."
