Product Type Specific: SHIP2 (INPPL1) phosphosite-specific antibody

Antibody Code: PN534

Antibody Target Type: Phosphosite-specific

Antibody Phosphosite: Y886

Protein UniProt: O15357

Protein SigNET: O15357

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human SHIP2 (INPPL1) sequence peptide Cat. No.: PE-04AES99

Antibody Immunogen Sequence: ERL(pY)EWI(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues E883 to I889; In the region between the Exo-endo_phos and SHAM_1 domains. This is one of the main in vivo phosphorylation sites in proteins.

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.This antibody was also subject to negative purification over phosphotyrosine-agarose.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: SHIP2 (INPPL1) is a 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. 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.
