Which protein is the Ca²⁺ sensor in synaptic transmission? A) Synapsin B) Munc18 C) Synaptotagmin D) Synaptobrevin

Question

Quizplus · Accepted Answer

The Ca²⁺ sensor in synaptic transmission is referring to the calcium sensor protein complex that is responsible for triggering neurotransmitter release. This complex includes the calcium binding protein synaptotagmin, which is the best choice among the given options. Synapsin and Munc18 are involved in regulating the release of neurotransmitters rather than directly sensing calcium. Synaptobrevin is a vesicle-associated membrane protein that plays a role in vesicle fusion with the presynaptic membrane.
