Protein Complex at Work

Caption

This illustration shows a protein complex at work in brain signaling. Its structure, which contains joined protein complexes known as SNARE and synaptotagmin-1, is shown in the foreground. This complex is responsible for the calcium-triggered release of neurotransmitters from our brain's nerve cells in a process called synaptic vesicle fusion. The SNARE structure is shown in blue, red, and green, and synaptotagmin-1 is shown in orange. The background image shows electrical signals traveling through a neuron.
