WD40 repeat proteins are key components of many essential biologic functions. They regulate the assembly of multiprotein complexes by presenting a beta-propeller platform for simultaneous and reversible protein-protein interactions. Members of the WIPI subfamily of WD40 repeat proteins, such as WIPI2, have a 7-bladed propeller structure and contain a conserved motif for interaction with phospholipids (Proikas-Cezanne et al., 2004 [PubMed 15602573]).[supplied by OMIM, Mar 2008]
GeneCards Summary for WIPI2 Gene
WIPI2 (WD Repeat Domain, Phosphoinositide Interacting 2) is a Protein Coding gene. Among its related pathways are Cellular Senescence and Regulation of autophagy. GO annotations related to this gene include phosphatidylinositol-3-phosphate binding and phosphatidylinositol-3,5-bisphosphate binding. An important paralog of this gene is WIPI1.
UniProtKB/Swiss-Prot for WIPI2 Gene
Early component of the autophagy machinery being involved in formation of preautophagosomal structures and their maturation into mature phagosomes in response to phosphatidylinositol 3-phosphate (PtdIns3P). May bind PtdIns3P.
Isoform 4: 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.
