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 (

INTERACTION

DNA

RNA

small molecule

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

cell & other

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
