SH2-domain containing inositol-5-phosphatase (SHIP) de-phosphorylates PI(3,4,5)P3 at the D5 position of the inositol ring to create PI(3,4)P2.
PMID:15713798
The phosphorylated third ITSM of 2B4 can recruit the phosphatases SHP-1, SHP-2, SHIP, and the inhibitory kinase Csk. SAP acts as an inhibitor of interactions between 2B4 and these negative regulatory molecules, explaining how 2B4 inhibits NK-cell activation in the absence of functional SAP.
PMID:15169881
2B4 signaling induces phosphorylation of SHIP1,VAV1,CBL.
This phosphorylation is dependent on SAP and FYN.
PMID:22683124
2B4-mediated inhibition was restored when SHIP-1 was reintroduced in SHIP-1-deficient cells.
In the NK cells lacking SHIP-1, there was a prominent diminution of the inhibitory influence of 2B4 (to ∼25% of control).
PMID:12393695
CD16 stimulation on human primary natural killer (NK) cells induces the rapid and transient translocation of SHIP-1 in the lipid-enriched plasma membrane microdomains, termed rafts, where it associates with tyrosine-phosphorylated zeta chain and shc adaptor protein.
SHIP1 inhinits NK cells activation via bloking of PI3K pathway. It hydrolyzes the 5′-phosphate of PI3,4,5P3l eading to its conversion to PI3,4P2.
PMID:20363967, PMID:16204085
Src homology 2-containing inositol 5'-phosphatase 1 negatively regulates IFN-gamma production by natural killer cells stimulated with antibody-coated tumor cells and interleukin-12, probably via inhibition of PI3K pathway and downstream ERK signaling.
PMID:11449354, PMID:12393695
CD16 cross-linking on human NK cells induces the association of SHIP-1 with receptor zeta-chain through the adaptor protein shc.
Fc gamma RIII alpha (CD16) autoregulates activation of downstream signals trough CD3 zeta/ Shc/ Inositol polyphosphate-5-phosphatase 145kDa ( SHIP ) pathway. The hypothetical mechanism consists of SHIP participation in inhibition of Ca('2+) -depend pathway and signal from PI3K via decreased amount IP3 [45] and PtdIns(3,4,5)P3.
PMID:1238444
FcgammaRIIa-mediated phagocytosis was significantly enhanced in THP-1 cells overexpressing dominant-negative form of SHIP in the absence of FcgammaRII(b). These results indicate that SHIP negatively regulates FcgammaR-mediated phagocytosis through all ITAM-containing IgG receptors
PMID:20435894
IL-10 inhibits miR-155 expression via STAT3. 3--UTR of SHIP1 is targeted by miR-155. Inhibition of Mir155 expression upregulates SHIP downstream of IL10
PMID:22955274
SHIP inhibit MAPKp38 activation and prevent MNK1 phosphorylation by inhibiting the p38 MAPK pathway downstream of IL10. MNK1 regulates TNFa mRNA polysome assembly and upregulates TNFa translation.IL-10 Inhibits TNF Translation through SHIP1-mediated Inhibition of Mnk1
PMID:21469115
IL4 signaling reduces SHIP protein levels and activity via PI3K correlating with M2 marker induction ( activation of arginase protein level and activity and inhibition of NO production).
