We present the genomic structure of the human glutamate transporter GLT-1 coding region, the intronic sequences adjacent to the exons, and oligonucleotide primer sequences for single strand conformational analysis. The exon-intron boundaries were determined using long-distance PCR and direct sequencing. The human GLT-1 coding region is composed of 10 exons spanning > 50 kb of genomic DNA. The exons range from 127 to 251 bp in length. The intron lengths vary considerably from 2.2 kb to > 15 kb. These data provide the basis for implementing a comprehensive screen for genetic alterations in the human GLT-1 gene using genomic DNA as a template.
