Abstract:
We have isolated a 3845 base-pair cDNA (BNGLUAS) encoding a bovine glutamate transporter (bovine GLAST) by screening a bovine retina cDNA library with an oligonucleotide probe corresponding to conserved regions of known glutamate transporters. The cDNA sequence predicted a protein of 542 amino acids and displayed 96% and 97% amino acid identity with the rat GLAST/GluT-1 and human GLAST, respectively. Expression of the bovine GLAST in Xenopus oocytes revealed Na(+)-dependent [14C]L-glutamate uptake and electrogenic glutamate uptake.
