The WIPF1 gene (WIPF1 stands for "WAS/WASL Interacting Protein Family Member 1") is a protein-coding gene located on chromosome 2q31.1.
The WIPF1 gene encodes a protein that plays an important role in the organization of the actin cytoskeleton. The protein binds to a region of the Wiskott-Aldrich syndrome protein that is frequently mutated in Wiskott-Aldrich syndrome. Impairment of the interaction between these two proteins appears to be etiologically significant for this disease. Two transcript variants encoding the same protein have been identified for this gene.
