HIP1 and synucleinopathy: We also investigated the levels HIP1 and MOBP proteins in other neurodegenerative disorders, including PD (N = 6) as another synucleinopathy, PSP (N = 6) as a disease in which variants in MOBP are a genetic risk factor and HD (N = 5) as a disease in which the mutant protein HTT is known to be a HIP1 interactor.
