Fukutin is a protein that in humans is encoded by the FKTN gene. It is necessary for the maintenance of muscle integrity, cortical histogenesis, and normal ocular development. In humans this protein is encoded by the FCMD gene (also named FKTN), located on chromosome 9q31. The FKTN gene encodes a type II transmembrane protein that is central to the Golgi apparatus through an N- terminal signal anchor. Fukutin is a crucial enzyme involved in modifying proteins, particularly alpha- dystroglycan, which links the cell's internal structure to the outside matrix, vital for muscle and brain health. It is suggested that Fukutin may be located in the extracellular matrix, where it interacts with a large complex encompassing both the inside and outside of muscle membranes.
