ATP6AP2 and Parkinson disease: For example, Parkinson’s disease can be linked to mutations in SV-resident proteins such as renin-receptor (121st rank), involved in SV acidification, dnajc13 (318th rank, SV endocytosis) and sv2c (97th rank, SV trafficking), or in SV-visitor proteins, such as synaptojanin-1 (351st rank, SV endocytosis) or pla2g6 (653rd rank, lipid composition) (Dataset S1).
