A Conserved Requirement for RME-8/DNAJC13 in Neuronal Autolysosome Reformation.

ABSTRACT: Autophagosomes fuse with lysosomes, forming autolysosomes that degrade engulfed cargo. To maintain lysosomal capacity, autolysosome reformation (ALR) must regenerate lysosomes from autolysosomes using a membrane tubule-based process. Maintaining lysosomal capacity is required to maintain proteostasis and cellular health, especially in neurons where lysosomal dysfunction has been repeatedly implicated in neurodegenerative disease. Cell biological studies have linked the DNA-J domain Hsc70 co-chaperone RME-8/DNAJC13 to endosomal coat protein regulation, while human genetics studies have linked RME-8/DNAJC13 to neurological disease, including Parkinsonism and Essential Tremor. We report new analysis of the requirements for the RME-8/DNAJC13 protein in neurons, focusing on C. elegans me
