Abstract

Desmin is the major intermediate filament protein in muscle cells and is one of the earliest myogenic markers of skeletal and cardiac muscle differentiation. The muscle-specific expression of desmin is regulated by a unique combination of transcriptional and epigenetic controls. Desmin protein functions in the maintenance of myofibril organization and structural and functional integrity of muscle. Loss-of-function studies in mice suggest an additional role for desmin in mitochondrial distribution, morphology, and function. Mutations in desmin or its chaperone protein αB-crystallin are associated with myopathy of skeletal and cardiac muscle. The desminopathies are characterized by the accumulation of intracellular desmin-positive protein inclusions and gain of function transgenic models show that mutations in desmin and αB-crystallin are autosomal dominant and sufficient to recapitulate the most important aspects of the human disease. Further study of these models has revealed that a large number of pathological processes are involved in disease development, which may provide starting points for targeting future therapeutic interventions.
