PS34 (vacuolar protein sorting 34), otherwise known as PI3-kinase type 3 (PIK3C3), is a ubiquitously expressed class III PI3K (phosphoinositide 3-kinase), and member of the PI3/PI4-kinase family, which specifically utilizes phosphatidylinositol (PtdIn) as a substrate, and functions as the catalytic subunit of the PI3K complex.
VPS34 plays a role in the transport of lysosomal enzyme precursors to lysosomes, and in endocytosis and vesicular trafficking, and has been strongly implicated as a regulator of autophagy, forming a multi-protein complex with the proautophagic tumor suppressors Beclin1/Atg6, Bif-1, and UVRAG, in the initiation of autophagosome formation.
Distinct complexes of VPS34 have been shown to regulate endocytic processes vital for late-stage autophagosome-lysosome fusion.
PS34 has been tested in immunofluorescence using HUVEC cells, in conjunction with Hoescht 33342 (blue) nuclear staining.
