The mouse dystonia musculorum gene is a neural isoform of bullous pemphigoid antigen 1

Abstract

Dystonia musculorum (dt) is a hereditary neurodegenerative disease in mice that leads to a sensory ataxia. We describe cloning of a candidate dt gene, dystonin, that is predominantly expressed in the dorsal root ganglia and other sites of neurodegeneration in dt mice. Dystonin encodes an N-terminal actin binding domain and a C-terminal portion comprised of the hemidesmosomal protein, bullous pemphigoid antigen 1 (bpag1). dt and bpag1 are part of the same transcription unit which is partially deleted in a transgenic strain of mice, Tg4, that harbours an insertional mutation at the dt locus, and in mice that carry a spontaneous dt mutation, dtAlb. We also demonstrate abnormal dystonin transcripts in a second dt mutant, dt24J. We conclude that mutations in the dystonin gene are the primary genetic lesion in dt mice.
