Function:May play an important role in phosphatidylinositol 3-kinase (PI3K) -AKT1 survival signaling. Substrate for AKT1 phosphorylation , but can also be activated by AKT1-independent mechanisms. Its role in survival signaling pathways may be modulated by oxidative stress. May also play a role in nerve growth factor-mediated neuroprotection. ,subcellular location:Found in the cytosolic fraction of the brain. ,subunit:The phosphorylated form interacts with 14-3-3. ,tissue specificity:Widely expressed with highest levels of expression in liver and heart. Expressed at higher levels in cancer cell lines (e.g. A549 and HeLa) than in normal cell lines (e.g. HEK293) . ,
