PI3KC3 Antibody (S851) - Protein Information

Name PIK3C3
Synonyms VPS34
Catalytic subunit of the PI3K complex that mediates formation of phosphatidylinositol 3-phosphate which plays a key role in initiation and maturation of autophagosomes. Involved in the transport of lysosomal enzyme precursors to lysosomes. Required for the abcission step in cytokinesis. Required for transport from early to late endosomes.
Cellular Location
Midbody. Late endosome. Note=Localizes also to discrete punctae along the ciliary axoneme and to the base of the ciliary axoneme.
Tissue Location
Ubiquitously expressed, with a highest expression in skeletal muscle.

Application Data

  • WB - PI3KC3 Antibody (S851) AP1851j

    Western blot analysis of anti-PI3KC3 Antibody (S851) (Cat.#AP1851j) in CEM cell line lysates (35ug/lane). PI3KC3 (arrow) was detected using the purified Pab.

  • IHC - PI3KC3 Antibody (S851) AP1851j

    Formalin-fixed and paraffin-embedded human skeletal muscle tissue reacted with PI3KC3 Antibody (S851), which was peroxidase-conjugated to the secondary antibody, followed by DAB staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated.

PI3KC3 is a catalytic subunit of the PI3K complex involved in the transport of lysosomal enzyme precursors to lysosomes. This enzyme acts catalytically to convert 1-phosphatidyl-1D-myo-inositol to 1-phosphatidyl-1D-myo-inositol 3-phosphate. Macroautophagy is the major inducible pathway for the general turnover of cytoplasmic constituents in eukaryotic cells, it is also responsible for the degradation of active cytoplasmic enzymes and organelles during nutrient starvation. Macroautophagy involves the formation of double-membrane bound autophagosomes which enclose the cytoplasmic constituent targeted for degradation in a membrane bound structure, which then fuse with the lysosome (or vacuole) releasing a single-membrane bound autophagic bodies which are then degraded within the lysosome (or vacuole). The regulation of the Beclin 1-PI3KC3 complex lipid kinase activity is a critical element in the autophagy signaling pathway.
