GABA transporter 1
View/Edit Human | View/Edit Mouse |
GABA transporter 1 (GAT1) also known as sodium- and chloride-dependent GABA transporter 1 is a protein that in humans is encoded by the SLC6A1 gene.[5][6]
Function
GAT1 a gamma-aminobutyric acid (GABA) transporter, which removes GABA from the synaptic cleft.[7] GABA Transporter 1 uses Na+ and Cl- to create a gradient, which removes or adds GABA to extracellular spaces in the cerebrum and cerebellum. The stoichiometry for GABA Transporter 1 is 2 Na+: 1 Cl-: 1 GABA. The activity of GAT1 is largely dependent on the presence of Na+, while Cl- assists by increasing the ability for GAT-1 to uptake GABA.[8]
Diseases
Research recorded in The American Journal of Psychiatry has shown that schizophrenia patients have GABA synthesis and expression altered, leading to the conclusion that GABA Transporter-1, which adds and removes GABA from the synaptic cleft, plays a role in the development of neurological disorders such as Schizophrenia.[9]
Interactions
SLC6A1 has been shown to interact with STX1A.[10][11][12]
