Heterogeneity of Matrin 3 in the developing and aging murine central nervous system.

ABSTRACT: Mutations in the MATR3 gene encoding the nucleotide binding protein Matrin 3 have recently been identified as causing a subset of familial amyotrophic lateral sclerosis (fALS) and more rarely causing distal myopathy. Translating the identification of MATR3 mutations into an understanding of disease pathogenesis and the creation of mouse models requires a complete understanding of normal Matrin 3 levels and distribution in vivo. Consequently, we examined the levels of murine Matrin 3 in body tissues and regions of the central nervous system (CNS). We observed a significant degree of variability in Matrin 3 protein levels among different tissues of adult animals, with the highest levels found in reproductive organs and the lowest in muscle. Within the adult CNS, Matrin 3 levels were lowest i
