Kinase PB (bahasa Inggris: protein kinase b, PKB, RAC, Akt) adalah kinase protein dari golongan kinase AGC yang menyebabkan inaktivasi glikogen sintase kinase-3.^[3]

Akt diaktivasi melalui lintasan receptor tyrosine kinase, seperti platelet-derived growth factor receptor (PDGF-R), insulin, epidermal growth factor (EGF), basic fibroblast growth factor (bFGF), and insulin-like growth factor I (IGF-I),^[4] dan merupakan substrat utama bagi PI3K.^[3] Senyawa fosfoinositida yang diproduksi oleh PI3K, yaitu fosfatidil inositol 3,4-bifosfat dan fosfatidil inositol 3,4,5-trisfosfat, akan mengikat pada domain pleckstrin homology (PH) dari Akt, hingga memungkinan translokasi Akt ke dalam sitoplasma untuk diaktivasi oleh PDK-1 dengan fosforilasi pada residu Thr-308 dan Ser-473.^[5] Akt juga teraktivasi oleh obat-obatan, toksin, radikal bebas seperti litium, asam valproat, clostridium difficile toxin, tert-butylhydroquinone, oksigen singlet, dan nitrogen monoksida.^[6] Pada sel saraf, miosit jantung, sel epitelial paru, aktivasi dapat diinduksi oleh simtoma seperti hipoksia, reoksigenasi, iskemia-reperfusi dan stres oksidatif.
