N2 - MDC1C and LGMD2I are two allelic forms of muscular dystrophies caused by mutations in the gene encoding for fukutin related protein (FKRP). FKRP encodes for a putative glycosyltransferase, the precise function of which is unknown. However, the marked reduction of alpha-dystroglycan glycosylation in the muscle of MDC1C and LGMD2I patients suggests a role for FKRP in dystroglycan processing. Using a polyclonal antibody raised against FKRP we now show that endogenous FKRP locates to the Golgi apparatus of neuronal, oligodendroglial, and the cardiac muscle cell line H9c2. In differentiated C2C12 myotubes and in transverse sections of normal skeletal and cardiac muscle, endogenous FKRP surrounded the myonuclei. This localisation was unaffected in the skeletal muscle of patients with MDC1C and LGMD2I carrying various FKRP mutations. These observations imply a specific role for FKRP during striated muscle, neuronal and glial development and suggest that protein mis-localisation is not a common mechanism of disease in FKRP-related dystrophies.
