Both PDK1 and PKB contain pleckstrin homology (PH) domains that interact with the PtdIns(3,4,5)P(3) second messenger. Disrupting the interaction of the PDK1 PH domain with phosphoinositides by expressing the PDK1 K465E knock-in mutation resulted in mice with reduced PKB activation. We explored the physiological consequences of this biochemical lesion in the central nervous system. The PDK1 knock-in mice displayed a reduced brain size due to a reduction in neuronal cell size rather than cell number. Reduced BDNF-induced phosphorylation of PKB at Thr308, the PDK1 site, was observed in the mutant neurons, which was not rate limiting for the phosphorylation of those PKB substrates governing neuronal survival and apoptosis, such as FOXO1 or glycogen synthase kinase 3 (GSK3). Accordingly, the integrity of the PDK1 PH domain was not essential to support the survival of different embryonic neuronal populations analyzed. In contrast, PKB-mediated phosphorylation of PRAS40 and TSC2, allowing optimal mTORC1 activation and brain-specific kinase (BRSK) protein synthesis, was markedly reduced in the mutant mice, leading to impaired neuronal growth and differentiation."xsd:string |
