This gene encodes a protein that plays an important role in the organization of the actin cytoskeleton. The encoded protein binds to a region of Wiskott-Aldrich syndrome protein that is frequently mutated in Wiskott-Aldrich syndrome, an X-linked recessive disorder. Impairment of the interaction between these two proteins may contribute to the disease. Two transcript variants encoding the same protein have been identified for this gene.,WIPF1,PRPL-2,WAS2,WASPIP,WIP,Signal Transduction,Cell Biology & Developmental Biology,Cytoskeleton,Microfilaments,WIPF1
