Role of ULK-FIP200 complex in mammalian autophagy: FIP200, a counterpart of yeast Atg17?

abstract：:SNCA/α-synuclein aggregation plays a crucial role in synucleinopathies such as Parkinson disease and dementia with Lewy bodies. Aggregating and nonaggregating SNCA species are degraded by the autophagy-lysosomal pathway (ALP). Previously, we have shown that the ALP is not only responsible for SNCA degradation but is a...
