Synaptotagmin-1 interacts with the SNARE protein syntaxin-1A and acidic phospholipids such as phosphatidylinositol 4,5-bisphosphate (PIP2). However, it is unclear how these interactions contribute to triggering membrane fusion. Using PC12 cells from Rattus norvegicus and artificial supported bilayers, we show that synaptotagmin-1 interacts with the polybasic linker region of syntaxin-1A independent of Ca2+ through PIP2. This interaction allows both Ca2+-binding sites of synaptotagmin-1 to bind to phosphatidylserine in the vesicle membrane upon Ca2+ triggering. We determined the crystal structure of the C2B domain of synaptotagmin-1 bound to phosphoserine, allowing development of a high-resolution model of synaptotagmin bridging two different membranes. Our results suggest that PIP2 clusters organized by syntaxin-1 act as molecular beacons for vesicle docking, with the subsequent Ca2+ influx bringing the vesicle membrane close enough for membrane fusion."],["dc.identifier.doi","10.1038/nsmb.2570"],["dc.identifier.gro","3142345"],["dc.identifier.isi","000319915900008"],["dc.identifier.pmid","23665582"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7253"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.issn","1545-9993"],["dc.title","Phosphatidylinositol 4,5-bisphosphate clusters act as molecular beacons for vesicle recruitment"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dspace.entity.type","Publication"]]
