PP1C and PP2A are p70S6K Phosphatases Whose Inhibition Ameliorates HLD12-Associated Inhibition of Oligodendroglial Cell Morphological Differentiation.

ABSTRACT: Myelin sheaths created by oligodendroglial cells encase neuronal axons to achieve saltatory conduction and protect axons. Pelizaeus-Merzbacher disease (PMD) is a prototypic, hereditary demyelinating oligodendroglial disease of the central nervous system (CNS), and is currently known as hypomyelinating leukodystrophy 1 (HLD1). HLD12 is an autosomal recessive disorder responsible for the gene that encodes vacuolar protein sorting-associated protein 11 homolog (VPS11). VPS11 is a member of the molecular group controlling the early endosome antigen 1 (EEA1)- and Rab7-positive vesicle-mediated protein trafficking to the lysosomal compartments. Herein, we show that the HLD12-associated Cys846-to-Gly (C846G) mutation of VPS11 leads to its aggregate formation with downregulated signaling through 7
