Overview
The SLC17A7 gene encodes Vesicular Glutamate Transporter 1 (VGLUT1), a critical protein responsible for packaging glutamate into synaptic vesicles in glutamatergic [neurons](/entities/neurons). VGLUT1 is the primary vesicular glutamate transporter in the forebrain and is essential for excitatory neurotransmission. It serves as a definitive marker for glutamatergic neurons and has become invaluable for mapping excitatory neural circuits in the brain.
Molecular Function
Glutamate Packaging
VGLUT1 actively transports glutamate into synaptic vesicles using a proton gradient:
Vesicle Loading: Critical for quantal size of glutamate release
Capacity: High-capacity glutamate transport
Transport Mechanism
