Abstract

In this chapter, we introduce a nanodisc-based experimental platform to study Ca <superscript>2+</superscript> -triggered membrane interaction of synaptotagmin-1. We describe and discuss in detail how to assemble this soluble mimetic of the docked vesicle-plasma membrane junction, with fluorescently labeled synaptotagmin-1 bound to trans SNAREpins assembled between nanodiscs and present the stopped-flow rapid mixing method used to monitor the conformational dynamics of Ca <superscript>2+</superscript> -activation process on a millisecond timescale.
