[Back to Kinase CK2a1]
Substrate: AKT1

Description: RAC-alpha serine/threonine-protein kinase (EC (RAC-PK-alpha)(Protein kinase B) (PKB) (C-AKT).

Synonyms: PKB, RAC

Ensembl ID: ENSG00000142208

UniprotKB/SwissProt: AKT1_HUMAN (P31749)

Function: General protein kinase capable of phosphorylating several known proteins. Phosphorylates TBC1D4. Signals downstream of phosphatidylinositol 3-kinase (PI(3)K) to mediate the effects of various growth factors such as platelet-derived growth factor (PDGF), epidermal growth factor (EGF), insulin and insulin-like growth factor I (IGF-I). Plays a role in glucose transport by mediating insulin-induced translocation of the GLUT4 glucose transporter to the cell surface. Mediates the antiapoptotic effects of IGF-I. Mediates insulin-stimulated protein synthesis, partly by playing a role in both insulin-induced phosphorylation of 4E-BP1 and in insulin-induced activation of p70 S6 kinase. Promotes glycogen synthesis by mediating the insulin-induced activation of glycogen synthase.
