General annotation (Comments)
| Function | Phosphatidylinositol (PtdIns) phosphatase that specifically hydrolyzes the 5-phosphate of phosphatidylinositol-3,4,5-trisphosphate (PtdIns(3,4,5)P3) to produce PtdIns(3,4)P2, thereby negatively regulating the PI3K (phosphoinositide 3-kinase) pathways. Plays a central role in regulation of PI3K-dependent insulin signaling, although the precise molecular mechanisms and signaling pathways remain unclear. While overexpression reduces both insulin-stimulated MAP kinase and Akt activation, its absence does not affect insulin signaling or GLUT4 trafficking. Confers resistance to dietary obesity. May act by regulating AKT2, but not AKT1, phosphorylation at the plasma membrane. Part of a signaling pathway that regulates actin cytoskeleton remodeling. Required for the maintenance and dynamic remodeling of actin structures as well as in endocytosis, having a major impact on ligand-induced EGFR internalization and degradation. Participates in regulation of cortical and submembraneous actin by hydrolyzing PtdIns(3,4,5)P3 thereby regulating membrane ruffling. Regulates cell adhesion and cell spreading. Required for HGF-mediated lamellipodium formation, cell scattering and spreading. Acts as a negative regulator of EPHA2 receptor endocytosis by inhibiting via PI3K-dependent Rac1 activation. Acts as a regulator of neuritogenesis by regulating PtdIns(3,4,5)P3 level and is required to form an initial protrusive pattern, and later, maintain proper neurite outgrowth. Acts as a negative regulator of the FC-gamma-RIIA receptor (FCGR2A). Mediates signaling from the FC-gamma-RIIB receptor (FCGR2B), playing a central role in terminating signal transduction from activating immune/hematopoietic cell receptor systems. Involved in EGF signaling pathway. Upon stimulation by EGF, it is recruited by EGFR and dephosphorylates PtdIns(3,4,5)P3. Plays a negative role in regulating the PI3K-PKB pathway, possibly by inhibiting PKB activity. Down-regulates Fc-gamma-R-mediated phagocytosis in macrophages independently of INPP5D/SHIP1. In macrophages, down-regulates NF-kappa-B-dependent gene transcription by regulating macrophage colony-stimulating factor (M-CSF)-induced signaling. May also hydrolyze PtdIns(1,3,4,5)P4, and could thus affect the levels of the higher inositol polyphosphates like InsP6. Ref.5 Ref.6 Ref.9 Ref.12 Ref.13 Ref.14 |
| Catalytic activity | 1-phosphatidyl-1D-myo-inositol 3,4,5-triphosphate + H2O = 1-phosphatidyl-1D-myo-inositol 3,4-diphosphate + phosphate. Ref.5 |
| Enzyme regulation | Activated upon translocation to the sites of synthesis of PtdIns(3,4,5)P3 in the membrane. Enzymatic activity is enhanced in the presence of phosphatidylserine By similarity. |
| Subunit structure | Interacts with tyrosine phosphorylated form of SHC1, Interacts with EGFR. Upon stimulation by the EGF signaling pathway, it forms a complex with SHC1 and EGFR. Interacts with cytoskeletal protein SORBS3/vinexin, promoting its localization to the periphery of cells. Forms a complex with filamin (FLNA or FLNB), actin, GPIb (GP1BA or GP1BB) that regulates cortical and submembraneous actin. Interacts with c-Met/MET, when c-Met/MET is phosphorylated on 'Tyr-1356'. Interacts with p130Cas/BCAR1. Interacts with CENTD3/ARAP3 via its SAM domain. Interacts with c-Cbl/CBL and CAP/SORBS1. Interacts with activated EPHA2 receptor. Interacts with receptors FCGR2A and FCGR2B. Interacts with tyrosine kinases ABL1 and TEC. Interacts with CSF1R. Ref.4 Ref.10 Ref.11 Ref.12 |
| Subcellular location | Cytoplasm › cytosol. Cytoplasm › cytoskeleton By similarity. Membrane; Peripheral membrane protein. Cell projection › filopodium By similarity. Cell projection › lamellipodium By similarity. Note: Translocates to membrane ruffles when activated, translocation is probably due to different mechanisms depending on the stimulus and cell type. Partly translocated via its SH2 domain which mediates interaction with tyrosine phosphorylated receptors such as the FC-gamma-RIIB receptor (FCGR2B). Tyrosine phosphorylation may also participate in membrane localization. Insulin specifically stimulates its redistribution from the cytosol to the plasma membrane. Recruited to the membrane following M-CSF stimulation. In activated spreading platelets, localizes with actin at filopodia, lamellipodia and the central actin ring. Ref.9 Ref.12 |
| Tissue specificity | Widely expressed. Ref.1 |
| Developmental stage | In E15.5 embryos, it is strongly expressed in the liver, specific regions of the central nervous system, the thymus, the lung, and the cartilage perichondrium. In adult it is markedly present in the brain and the thymus and at different stages of spermatozoa maturation in the seminiferous tubules. Ref.1 |
| Induction | Overexpressed in diabetic db/db mice. Ref.8 |
| Domain | The SH2 domain interacts with tyrosine phosphorylated forms of proteins such as SHC1 or FCGR2A. It also mediates the interaction with p130Cas/BCAR1 By similarity. The NPXY sequence motif found in many tyrosine-phosphorylated proteins is required for the specific binding of the PID domain By similarity. |
| Post-translational modification | Tyrosine phosphorylated by the members of the SRC family after exposure to a diverse array of extracellular stimuli such as insulin, growth factors such as EGF or PDGF, chemokines, integrin ligands and hypertonic and oxidative stress. May be phosphorylated upon IgG receptor FCGR2B-binding. Phosphorylated at Tyr-987 following cell attachment and spreading. Phosphorylated at Tyr-1161 following EGF signaling pathway stimulation By similarity. Ref.4 Ref.12 |
| Disruption phenotype | Mice are viable, have normal glucose and insulin levels, and normal insulin and glucose tolerance. They are however highly resistant to weight gain when placed on a high-fat diet, suggesting that inhibition of Inppl1 would be useful in the effort to ameliorate diet-induced obesity. According to preliminary results from Ref.6, mice display increased sensitivity to insulin, characterized by severe neonatal hypoglycemia, deregulated expression of the genes involved in gluconeogenesis, and perinatal death. They display increased glucose tolerance and insulin sensitivity associated with an increased recruitment of the Slc2a4/Glut4 glucose transporter and increased glycogen synthesis in skeletal muscles. However, these knockout mice also contain a deletion of the last exon of Phox2a gene. It is therefore unknown whether the insulin sensitivity observed in these mice result from inactivation of either Inppl1 or Phox2a. Ref.6 Ref.13 |
| Sequence similarities | Belongs to the inositol 1,4,5-trisphosphate 5-phosphatase family. Contains 1 SAM (sterile alpha motif) domain. Contains 1 SH2 domain. |
| Sequence caution | The sequence AAI19454.1 differs from that shown. Reason: Erroneous initiation. |
