Antibody Code: NP044-2
Antibody Target Type: Pan-specific
Protein UniProt: Q92835
Protein SigNET: SHIP1
Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human SHIP1 (INPP5D) sequence peptide Cat. No.: PE-01BBQ70
Antibody Immunogen Sequence: CKELYGEVIRTLPSLE
Antibody Immunogen Description: Corresponds to amino acid residues C217 to E232.
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: SHIP1 (SH2 domain-containing inositol 5-phosphatase 1; INPP5D) 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, to negatively regulate PI3K (phosphoinositide 3-kinase) pathways. It acts as a negative regulator of B-cell antigen receptor signalling, and mediates signalling from the FC-gamma-RIIB receptor (FCGR2B) as well as a negative regulator of myeloid cell proliferation/survival and chemotaxis, neutrophil migration, mast cell degranulation, immune cells homeostasis, integrin alpha-IIb/beta-3 signalling in platelets and JNK signalling in B-cells. It regulates proliferation of osteoclast precursors, macrophage programming, phagocytosis and activation and is required for endotoxin tolerance. It may also hydrolyze PtdIns(1,3,4,5)P4. It interacts with adaptor proteins such as SHC, GABs, and DOKs. It features an N-terminal SH2 domain, a central catalytic 5-phosphatase domain, and a C-terminal proline-rich region. SHIP1 is primarily expressed in immune cells like B cells, mast cells, and myeloid cells. Primarily cytoplasmic but recruited to the plasma membrane upon receptor activation. It is expressed in microglial cells, where it regulates immune response, making it a key risk factor and therapeutic target for Alzheimer's disease.
