  • 功能：
    Component of the autophagy machinery that controls the major intracellular degradation process by which cytoplasmic materials are packaged into autophagosomes and delivered to lysosomes for degradation. Involved in an early step of the formation of preautophagosomal structures. Binds and is activated by phosphatidylinositol 3-phosphate (PtdIns3P) forming on membranes of the endoplasmic reticulum upon activation of the upstream ULK1 and PI3 kinases. Mediates ER-isolation membranes contacts by interacting with the ULK1:RB1CC1 complex and PtdIns3P. Once activated, WIPI2 recruits at phagophore assembly sites the ATG12-ATG5-ATG16L1 complex that directly controls the elongation of the nascent autophagosomal membrane.; Recruits the ATG12-ATG5-ATG16L1 complex to omegasomes and preautophagosomal structures, resulting in ATG8 family proteins lipidation and starvation-induced autophagy. Isoform 4 is also required for autophagic clearance of pathogenic bacteria. Isoform 4 binds the membrane surrounding Salmonella and recruits the ATG12-5-16L1 complex, initiating LC3 conjugation, autophagosomal membrane formation, and engulfment of Salmonella.

    1. Data suggest that, in patients with diabetic kidney disease, urinary excretion of mRNAs for MAP1LC3A, WIPI2, and RB1CC1 is down-regulated as compared to healthy control subjects; these transcripts may serve as urinary autophagy biomarkers. (MAP1LC3A = microtubule associated protein 1 light chain 3; WIPI2 = WD repeat domain phosphoinositide-interacting protein 2; RB1CC1 = RB1 inducible coiled-coil 1) PMID: 28760651
    2. Here the s show that recruitment of WIPI2, itself essential for anti-bacterial autophagy, is dependent on the localization of catalytically active TBK1 to the vicinity of cytosolic bacteria. PMID: 27370208
    3. The specific autophagosomal localization of both WIPI1 and WIPI2 (refered to as WIPI puncta) has been employed to assess autophagy using fluorescence microscopy methods, such as confocal and live-cell video microscopy PMID: 25462558
    4. Data suggest WIPI1/WIPI2 co-localize with microtubule-associated light chain 3 and autophagy related proteins 2/14L, participate in biogenesis of phagosomes, autophagy, and mobilization of lipids to/from intracellular droplets. [review-like article] PMID: 25233424

    6. Data suggest that WIPI2b directly interacts with dimer of ATG16L1 (autophagy related 16-like 1) and this interaction is linked to production of phosphatidylinositol 3-phosphate in endoplasmic reticulum triggered by autophagosome formation. [REVIEW] PMID: 25233411
