The WIPI protein family (WD-repeat protein Interacting with PhosphoInositides) is an evolutionarily conserved family of proteins.[1] WIPI proteins contain a WD repeat domain that folds into a 7-bladed beta-propeller that functions in autophagy,[1] and contain a conserved motif for interaction with phospholipids.[2]

Members of this family include:
