    basic FUNCTION
  • regulate the assembly of multiprotein complexes by presenting a beta-propeller platform for simultaneous and reversible protein-protein interactions
  • WIPI1 and WIPI2 as novel protein components of autophagosomes, and of membrane sites from which autophagosomes might originate (ER, PM, Golgi area)
  • WIPI proteins function as essential phosphatidylinositol 3-phosphate (PtdIns3P) effectors at the nascent autophagosome
  • WIPI2 protein level regulated by MTORC1 and HUWE1 is a pivotal determinant of cellular autophagy intensity
  • robust mechanism for autophagosome formation in which WIPI2 may be one component of the preferential, but not sole, machinery with the potential to orchestrate autophagosome formation (

    protein
  • WIPI2 is a phosphorylation substrate of CRTC1 and a ubiquitination target of HUWE1
  • interface between WIPI2 and ATG16L1 mediates autophagosome formation under starvation conditions
  • WIPI2 binds to and promotes AAA-ATPase VCP/p97 to damaged mitochondria

    REGULATION
    Other dynamic and local phosphorylation of WIPI2 is a critical regulatory step in autophagosome biogenesis in neurons and this step is specifically affected by aging
