background:
Plays a role as a key modulator of the AKT-mTOR signaling pathway controlling the tempo of the process of newborn neurons integration during adult neurogenesis, including correct neuron positioning, dendritic development and synapse formation. Enhances phosphoinositide 3-kinase (PI3K)-dependent phosphorylation and kinase activity of AKT1/PKB, but does not possess kinase activity itself. Phosphorylation of AKT1/PKB thereby induces the phosphorylation of downstream effectors GSK3 and FOXO1/FKHR, and regulates DNA replication and cell proliferation (By similarity). Essential for the integrity of the actin cytoskeleton and for cell migration. Required for formation of actin stress fibers and lamellipodia. May be involved in membrane sorting in the early endosome.

Subunit:
Interacts (via SLCterminus) with DISC1; the interaction is direct. Interacts with AKT proteins; the interaction is inhibited in presence of DISC1. Homodimer. The non-phosphorylated form interacts with phosphatidylinositol 4-phosphate [PI(4)P] and weakly with phosphatidylinositol 3-phosphate [PI(3)P]. Interacts with microtubules. Interacts with actin through its SLCterminal domain. Interacts with the SLCterminus of AKT1/PKB.
Subcellular Location:
Membrane. Cell membrane. Cytoplasm, cytosol. Cytoplasmic vesicle. Cell projection, lamellipodium. Note=Localizes to the cell membrane through interaction with phosphoinositides.
Tissue Specificity:
Expressed ubiquitously.
Post-translational modifications:
Phosphorylation is induced by epidermal growth factor (EGF) in a phosphoinositide 3-kinase (PI3K)-dependent manner. Phosphorylation by AKT1/PKB is necessary for the delocalization from the cell membrane and for cell migration.
Similarity:
Belongs to the CCDC88 family.
