SHIP2 (inositol polyphosphate-5 phosphatase-like 1), contains a phosphatase domain and an SH2 (src-homology domain 2) motif. SHIP2 iswidely expressed in fibroblast and nonhematopoietic tumor cell lines. Tyrosine phosphorylation of SHIP2 occurrs in response to treatment of cells with EGF, platelet-derived growth factor (PDGF), nerve growth factor (NGF), insulin-like growth factor-1 (IGF1), or insulin. EGF and PDGF induces transient tyrosine phosphorylation of SHIP2, while treatment of cells with NGF, IGF1, or insulin results in prolonged tyrosine phosphorylation of SHIP2, indicaating that SHIP2 may play a significant role in regulation of phosphatidylinositol 3-prime-kinase signaling by growth factors and insulin. Some animal models indicate that SHIP2 is a potent negative regulator of insulin signaling and insulin sensitivity in vivo, while others suggest that SHIP2 mediates obesity resistance but not changes in glucose and insulin homeostasis.
Peptides are lyophilized in a solid powder format. Peptides can be reconstituted in solution using the appropriate buffer as needed.
Target:
The synthetic peptide sequence used to generate the antibody AP8473d was selected from the N-term region of human SHIP2. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.
