EAAT2/GLT1 Proteins and Enzymes

GLT1 is the major glial glutamate transporter that takes up more than 90% of glutamate from the synapse. GLT1b is a splice variant that contains 11 unique amino acids at the C-terminus that encode a PDZ binding domain. GLT1b was initially believed to be the neuronal isoform of GLT1, but it now appears that GLT1b is localized to astrocytes in the no...
