Defective ATP13A2-ITCH-ALIX signaling impairs intraluminal vesicle biogenesis and increases neuronal vulnerability.
ATP13A2 is a lysosomal P5B-type ATPase whose loss-of-function mutations are associated with a spectrum of neurodegenerative disorders, including early-onset Parkinson's disease, Kufor-Rakeb syndrome, neuronal ceroid lipofuscinosis, hereditary spastic paraplegia, and amyotrophic lateral sclerosis. Although ATP13A2 is kn...
