Vacuolar protein sorting 34 (VPS34), also known as phosphatidylinositol 3-kinase catalytic subunit type 3 (PIK3C3), is encoded by the gene mapped to human chromosome 18q12.3. The encoded protein belongs to the phosphoinositide (PI)-3-kinase family. VPS34 is widely expressed in all tissues of mammals.
免疫原
synthetic peptide corresponding to amino acids 22-34 of human VPS34, conjugated to KLH via an added cysteine residue. The corresponding sequence is identical in mouse and rat.
應用
Anti-VPS34 antibody produced in rabbit has been used in immunoblotting.[1]
生化/生理作用
Vacuolar protein sorting 34 (VPS34) is a lipid kinase that phosphorylate phosphatidylinositol (PtdIns), to form phosphatidylinositol 3 phosphate (PtdIns3P). VPS34 plays a vital role in various intracellular trafficking events such as autophagy and phagosome formation. Thus, the inhibition of kinase activity of Vps34 might be considered as a potential therapeutic method for cancer treatment. VPS34 is also involved in internal vesicle formation within multivesicular endosomes, reverse transport of endosome to Golgi apparatus and membrane transport from the outer nuclear membrane towards the cell periphery. Mutation in the gene encoding VPS34 is associated with pathogenesis of schizophrenia. VPS34 plays an essential role in nutrient/amino acid induced activation of mechanistic target of rapamycin (mTOR) signaling in cultured cells and it also facilitates early embryogenesis and cell proliferation.

Gaucher disease, the inherited deficiency of lysosomal glucocerebrosidase, is characterized by the presence of glucosylcer-amide macrophages, the accumulation of glucosylceramide in lysosomes and the secretion of inflammatory cytokines. However, the connection between this lysosomal storage and inflammation is not clear.
Here we present a detailed genetic analysis of let-512/vps34 that encodes the Caenorhabditis elegans homologue of the yeast phosphatidylinositol 3-kinase Vps34p. LET-512/VPS34 has essential functions and is ubiquitously expressed in all tissues and developmental stages. It accumulates at a perinuclear
The PIK3C3 gene has been implicated as a candidate gene for schizophrenia by functional evidence and genetic association studies. A series of previous studies have found susceptibility SNPs in promoter region. To further verify its susceptibility to schizophrenia in the

Vps34 (the human class III phosphoinositide 3-kinase) is a lipid kinase involved in vesicle trafficking and autophagy and therefore constitutes an interesting target for cancer treatment. Because of the lack of specific Vps34 kinase inhibitors, we aimed to identify such
