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（WD repeat domain, phosphoinositide interacting 2）, have a 7-bladed propeller structure and contain a conserved motif for interaction with phospholipids .蛋白别名为：WD repeat domain phosphoinositide-interacting protein 2 (WIPI-2) (WIPI49-like protein 2);基因ID为：26100；蛋白质ID:Q9Y4P8
