Antibody Immunogen Source: Human PIP5K sequence peptide Cat. No.: PE-04AOO99
Antibody Immunogen Sequence: RSA(pS)ITN(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues R304 to N310; in the region between the FYVE and DEP domains in the N-terminal part of the kinase.S307 phosphorylation stimulates the ability of PIKFYVE to catalyze the phosphorylation of phosphatidylinositol 3-phosphate on the fifth hydroxyl of the myo- inositol ring, to form phosphatidylinositol 3,5-bisphosphate. This is one of the major in vivo phosphorylation sites in PIP5K (≥199 reports from high throughput mass spectrometry studies recorded in PhosphoSitePlus). PIP5K is known to be phosphorylated at this site in vitro by Akt1 (PKBa), and AMPKa1 (PRKAA1).
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: PIP5K (PIKFYVE) is a protein-serine/threonine kinase of the Atypical group. It regulates the production and degradation of phosphatidylinositol 3,5-bisphosphate. The PI(3,5)P2 regulatory complex regulates both the synthesis and turnover of phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2). It catalyzes the phosphorylation of phosphatidylinositol 3-phosphate on the fifth hydroxyl of the myo-inositol ring, to form phosphatidylinositol 3,5-bisphosphate. It is required for endocytic-vacuolar pathway and nuclear migration, and plays a role in the biogenesis of endosome carrier vesicles (ECV)/ multivesicular bodies (MVB) transport intermediates from early endosomes. A PIP5K inhibitor, YM201636, significantly increased the survival of C9ORF72 patient- derived motor neurons by converting PtdIns3P into PtdIns(3,5)P2, which enhanced the fusion of lysosomes with both endosomes and autophagosomes under cell stress (1).
