Detection of Human SHIP2 by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human SHIP2 Monoclonal Antibody (Catalog # MAB5389) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for SHIP2 at approximately 140 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

SHIP2 in PC‑3 Human Cell Line. SHIP2 was detected in immersion fixed PC-3 human prostate cancer cell line using Mouse Anti-Human SHIP2 Monoclonal Antibody (Catalog # MAB5389) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red, upper panel; Catalog # NL007) and counterstained with DAPI (blue, lower panel). Specific staining was localized to nuclei and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: SHIP2

SHIP2 (SH2 domain-containing inositol 5-phosphatase 2; also inositol polyphosphate phosphatase-like 1) is a 160 kDa member of the phosphatidylinositol/PtdIns 5-phosphatase family of enzymes. It is widely expressed and negatively regulates PI3 kinase pathways by hydrolyzing the 5-phosphate of PtdIns-3,4,5-triphosphate. Human SHIP2 is 1258 amino acids (aa) in length. It contains one SH2 domain (aa 21-117), a Pro-rich region with an SH3 binding site (aa 935-1105), and a SAM (or sterile alpha -motif) domain that binds ARAP3 (aa 1196-1258). Phosphorylation is known to occur on Tyr986, 1162 and 1358, and on Thr958. There is an alternate start site at Met243 and a second splice variant that shows a 40 aa substitution for aa 1228-1258. Over aa 1106-1258, human SHIP2 shares 95% aa identity with mouse SHIP2.
