Several key proteins are involved in the regulation and function of the RRP. These include:
1. [SNARE proteins](https://): These proteins, such as [synaptobrevin](https://), [syntaxin](https://), and [SNAP-25](https://), form a complex that mediates the docking and fusion of vesicles with the plasma membrane. 2. [Synaptotagmin](https://): This protein acts as a calcium sensor and triggers the rapid fusion of vesicles in response to calcium influx. 3. [Munc18](https://) and [Munc13](https://): These proteins are involved in the priming of vesicles, preparing them for rapid release upon stimulation.
