3.1.3.86 phosphatidylinositol-3,4,5-trisphosphate 5-phosphataseIUBMB Comments
This enzyme hydrolyses 1-phosphatidyl-1D-myo-inositol 3,4,5-trisphosphate (PtdIns(3,4,5)P3) to produce PtdIns(3,4)P2, thereby negatively regulating the PI3K (phosphoinositide 3-kinase) pathways. The enzyme also shows activity toward (PtdIns(1,3,4,5)P4) . The enzyme is involved in several signal transduction pathways in the immune system leading to an adverse range of effects.

COMMENTARY
LITERATURE
malfunction
physiological function
malfunction
-
cell adhesion to collagen-I-coated dishes is decreased in SHIP2-deicient MEF cells compared with wild type cells
malfunction
-
depletion of SHIP 5'-phosphatases increases neutrophil wound attraction and random motility through a PI3K-dependent pathway. Ectopic expression of the SHIP1 phosphatase domain impairs neutrophil migration
malfunction
-
enzyme mutations are associated with opsismodysplasia. Mice expressing a germline catalytically inactive SHIP2 mutant protein are viable, but have defects in the development of muscle, adipose tissue and the female genital tract, as well as in somatic growth
malfunction
-
disruption of the enzyme-Mena interaction in cancer cells leads to attenuated capacity for extracellular matrix degradation and invasion in vitro, as well as reduced metastasis in vivo
malfunction
-
apoptosis in MDA-MB-231 cells is increased in SHIP2-depleted cells as compared to control cells
malfunction
-
enzyme deficiency leads to myeloproliferation and B-cell lymphoma in mice; enzyme deficiency leads to myeloproliferation and B-cell lymphoma in mice
malfunction
-
isoform SHIP2 inhibition or knockdown inhibits cell migration and reduces phosphorylated protein kinase B levels, resulting in sensitivity to chemotherapeutics
physiological function
-
isoforms SHIP2 and SHIP1 have a different hierarchy of binding SH3-domain containing proteins; isoforms SHIP2 and SHIP1 have a different hierarchy of binding SH3-domain containing proteins
physiological function
-
PR130/Balpha1 and SHIP2 partially colocalize in untreated HeLa cells, and both translocate to the cell membrane on epidermal growth factor stimulation. Protein phosphatase 2A PR130/Balpha1 subunit binds to the SH2 domain-containing inositol polyphosphate 5-phosphatase 2 and prevents epidermal growth factor-induced epidermal growth factor receptor degradation sustaining epidermal growth factor-mediated signaling
physiological function
-
SHIP2 interaction with vinexin alpha promotes the localization of SHIP2 at the periphery of the cells leaving its catalytic site intact. SHIP2 is active both as a PtdIns(3,4,5)P3 5-phosphatase and as a modulator of focal contact formation
physiological function
-
SHIP is involved in platelet activation evoked by thrombin
physiological function
-
the Src homology 2 domain containing inositol 5-phosphatase SHIP2 is recruited to the epidermal growth factor receptor and dephosphorylates phosphatidylinositol 3,4,5-trisphosphate in epidermal growth factor-stimulated COS-7 cells
physiological function
-
SHIP phosphatases serve as a brake that limit neutrophil motility and inflammation, at least in part through their effects on PI3K signaling
physiological function
-
overexpression of the wild-ype SHIP2 gene leads to a higher total lipid content (28%) compared to control, whereas overexpression of the dominant negative SHIP2 gene reduces total lipid content in oleate treated cells by 40%. Overexpression of SHIP2 wild-type also leads to a significant increase in both secretion of apoB100 containing lipoproteins and de novo lipogenesis. Overexpression of the SHIP2 dominant negative gene prevents oleate-induced de novo lipogenesis and secretion of apoB100 containing lipoproteins in HepG2 cells
physiological function
-
isoform SHIP1 inhibits haematopoietic cell proliferation, inhibits Akt signalling and regulates immune cell function in vitro and in vivo; isoform SHIP2 regulates Akt signalling in metabolic tissues
physiological function
-
high glucose induces SHIP2 mRNA and protein levels in HepG2 cells. Overexpression of a dominant negative mutant SHIP2 ameliorates high glucose-induced de novo lipogenesis and secretion of apoB containing lipoprotein in HepG2 cells. Overexpression of the SHIP2 dominant negative mutant decreases high glucose-induced apoB containing lipoproteins secretion via reduction in reactive oxygen species generation, JNK phosphorylation and Akt activation. AMPK/mTOR/SREBP1 is the signaling pathway that mediates the effects of SHIP2 modulation on hepatic de novo lipogenesis
physiological function
-
the enzyme SHIP2 recruits Mena, but not vasodilator-stimulated phosphoprotein, to invadopodia
physiological function
-
the enzyme's activity controls 1-phosphatidyl-1D-myo-inositol 3,4,5-trisphosphate binding by RAP1 and, thus, transcriptional silencing of variant surface glycoprotein genes
physiological function
-
the enzyme acts as a negative regulator of immune response and haematopoietic progenitor cell proliferation/survival, and as an inducer of cellular apoptosis. Isoform SHIP-1 is also implicated both as a haematopoietic tumour suppressor and activator; the enzyme acts as a negative regulator of immune response and haematopoietic progenitor cell proliferation/survival, and as an inducer of cellular apoptosis. Isoform SHIP-2 is a negative regulator of glucose homeostasis and is involved in the maturation and activation of mast cells as well as in phagocytosis directed by Fc receptors for immunoglobulin G, thus regulating allergic reactions and antibacterial defense
physiological function
-
isoform SHIP2 functions as oncogene in colorectal cancer by regulating protein kinase B activation

isoforms SHIP2 and SHIP1 are constitutively tyrosine phosphorylated in chronic myelogenous leukemia progenitor cells; isoforms SHIP2 and SHIP1 are constitutively tyrosine phosphorylated in chronic myelogenous leukemia progenitor cells. Stimulation of human hematopoietic growth factor responsive cell lines with stem cell factor, interleukin-3, and granulocyte-macrophage colony-stimulating factor leads to rapid tyrosine phosphorylation of SHIP2 and its resulting association with src homologous and collagen gene
