General annotation (Comments)
| Function | 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 By similarity. 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. Ref.1 Ref.8 |
| Subunit structure | Homodimer. The non-phosphorylated form interacts with phosphatidylinositol 4-phosphate [Pi4P] and weakly with phosphatidylinositol 3-phosphate [Pi3P] By similarity. Interacts with microtubules. Interacts AKT1/PKB (via C-terminus). Interacts (via C-terminus) with DISC1; the interaction is direct. Interacts with AKT proteins; the interaction is inhibited in presence of DISC1. Ref.1 Ref.5 Ref.8 UniProtKB Q3V6T2 |
| Subcellular location | Membrane. Cell membrane. Cytoplasm › cytosol. Cytoplasmic vesicle. Cell projection › lamellipodium By similarity. Note: Localizes to the cell membrane through interaction with phosphoinositides By similarity. |
| Tissue specificity | Expressed in the dentate gyrus, pyramidal cell layer of hippocampal regions CA1 and CA3 at postnatal 15. Expressed highly in neurons. Weakly in neuron progenitors (at protein level). Expressed in the dentate granule cell layer of the hippocampus. Expressed highly in the adult testis, moderately in the brain and at a low level in the spleen, lungs and fat. Ref.1 Ref.5 Ref.8 |
| Developmental stage | Temporally and spatially restricted during embryogenesis. At E10.5, expressed in the branchial arches, nasal processes, limbs, somites and dorsal root ganglia. At E11.5, expression persists at these sites in addition to the eye and fore-, mid- and hindbrain. By E12.5, expressed in the interdigital mesenchyme of the limbs. At E13.5, expression in the limbs flanks the digits and also appears in a subset of tendons in the hind- and forelimbs. Ref.5 |
| Post-translational modification | 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 By similarity. UniProtKB Q3V6T2 |
| Sequence similarities | Belongs to the CCDC88 family. |
| Sequence caution | The sequence AAH37020.1 differs from that shown. Reason: Erroneous initiation. The sequence CAI24877.1 differs from that shown. Reason: Erroneous gene model prediction. |
