Deciphering the complexity of the membrane-binding behavior of \u03b1-syn is crucial to understand its functions and the pathology of PD. Here, we used single-molecule imaging to show that \u03b1-syn forms multimers on lipid membranes with huge intermultimer distances. The multimers are characterized by self-limiting growth, manifesting in concentration-dependent exchanges of monomers, which are fast at micromolar concentrations and almost stop at nanomolar concentrations. We further uncovered movement patterns of \u03b1-syn\u2019s occasional trapping on membranes, which may be attributed to sparse lipid packing defects. Mutations such as E46K and E35K may disrupt the limit on the growth, resulting in larger multimers and accelerated amyloid fibril formation. This work emphasizes sophisticated regulation of \u03b1-syn multimerization on membranes as a critical underlying factor in the PD pathology.<\/jats:p>","DOI":"10.1126\/sciadv.ado4893","type":"journal-article","created":{"date-parts":[[2024,10,9]],"date-time":"2024-10-09T13:58:51Z","timestamp":1728482331000},"update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":14,"title":["Self-limiting
