Proteins that are subject to LLPS comprise some of the key players in the field of neurodegeneration, including Tau (implicated in Alzheimer’s disease), TDP43 and FUS (implicated in amyotrophic lateral sclerosis), Huntingtin (implicated in Huntington’s disease) and α-synuclein (implicated in Parkinson’s disease) [206,207]. This evidence concerns the gene MAPT and Alzheimer disease.
