Target Alias: 51C protein; Inositol polyphosphate 5-phosphatase; Inositol polyphosphate phosphatase-like 1; SH2-containing inositol 5-phosphatase 2; SHIP2
Product Type Specific: SHIP2 (NPPL1) protein phosphatase pan-specific antibody
Antibody Code: NP045-2
Antibody Target Type: Pan-specific
Protein UniProt: O15357
Protein SigNET: SHIP2
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human SHIP2 (INPPL1) sequence peptide Cat. No.: PE-01BBT99
Antibody Immunogen Sequence: CRRLHSEVDKVLSGLE
Antibody Immunogen Description: Corresponds to amino acid residues C215 to E230.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: SHIP2 (Src homology 2 domain-containing inositol 5-phosphatase 2; INPPL1) is a 140 kDa 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, and negatively regulate the PI3K (phosphoinositide 3-kinase) pathways. It features an N-terminal SH2 domain, a central 5-phosphatase catalytic domain, and a C-terminal proline-rich domain (containing PXXP and NPXY motifs). SHIP2 interacts with proteins like filamin and vinexin to regulate cell spreading, adhesion, and endocytosis. It is essential for maintaining actin structure and membrane ruffle formation. SHIP2 is expressed ubiquitously, with high levels in the skeletal muscle, heart, and brain. While overexpression reduces both insulin-stimulated MAP kinase and Akt activation, its absence does not affect insulin signalling or GLUT4 trafficking. It confers resistance to dietary obesity. It may also hydrolyze PtdIns(1,3,4,5)P4. Mutations in SHIP2 are associated with opsismodysplasia, a skeletal development disorder.
