Usage
For Research Use Only. Not for use in diagnostic or therapeutic procedures.
Regulatory subunit of the PI3K complex that mediates formation of phosphatidylinositol 3-phosphate; different complex forms are believed to play a role in multiple membrane trafficking pathways: PI3KC3-C1 is involved in initiation of autophagosomes and PI3KC3-C2 in maturation of autophagosomes and endocytosis. Involved in regulation of degradative endocytic trafficking and cytokinesis, probably in the context of PI3KC3-C2.
Gene References into Functions
A missense mutation in PIK3R4 (phosphoinositide 3-kinase regulatory subunit 4, named VPS15) in a family with a ciliopathy phenotype is identified. Besides being required for trafficking and autophagy, we show that VPS15 regulates primary cilium length in human fibroblasts.PMID:27882921
Both Danon Disease and glycogen storage disease type II show accumulation and altered localization of VPS15 in autophagy-incompetent fibers. However, TFEB displays a different pattern between these two lysosomal storage diseasesPMID:28102838
High expression of PI3K core complex genes is associated with poor prognosis in chronic lymphocytic leukemia.PMID:25840748
A specific sub-complex containing VPS15, VPS34, Beclin 1, UVRAG and BIF-1 regulates both receptor degradation and cytokinesis, whereas ATG14L, a PI3K-III subunit involved in autophagy, is not required.PMID:20643123
