FUZ is the human homolog of Drosophila fy protein and belongs to the fuzzy family. The fy gene of Drosophila encodes a novel four-pass transmembrane protein that plays two roles in the development of hairs on the Drosophila wing. The first is to specify the correct orientation of the hair by restricting its initiation to the distal vertex of the cell. The second role is to permit the development of just a single cell hair by maintaining the integrity of the F-actin and microtubule arrays that are required for hair development. In humans, the protein is involved in cytoskeleton function and cell polarity in epithelial cells. The human fuz gene is localized on chromosome 19q13.33.
