AKT3 and cancer: In addition, emerging evidence indicated the potential therapeutic value of tumor-related functional peptides encoded by circRNAs, especially cancer-inhibiting peptides/proteins, such as β-catenin-370aa encoded by circβ-catenin, circPPP1R12A-73aa by circPPP1R12A, and AKT3-174aa by circ-AKT3 [119].
