    Rab5 and Alsin regulate stress-activated cytoprotective signaling on mitochondria

    FoSheng Hsu, Stephanie Spannl ... Marino Zerial
    Oxidative stress leads to the translocation of Rab5 from endosome to mitochondria, regulated by ALS/Alsin, a component associated with amyotrophic lateral sclerosis, leading to mitochondrial-endosomal physical contacts and a cytoprotective response.
