Immunofluorescent analysis of PI3KC3 showing staining in the cytoplasm of U-251 cells. U251 cells were treated with Chloroquine (50uM,16h), fixed with 4% PFA (20 min) and permeabilized with Triton X-100 (0.2%, 30 min). Cells were probed with a PI3KC3 polyclonal antibody (Product # PA5-35215) (1:100, 2h at room temperature) followed by detection using a fluorescent conjugated secondary antibody (green) (1:1000, 1h). Nuclei were stained with Hoechst 33342 (blue) (10 ug/ml, 5 min).

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.
