碩士 / 國立清華大學 / 輻射生物研究所 / 84 / Glutamate plays an important role in the excitatory
transmission system in the mammalian brain. Glutamate
receptors may participate in basic functions of the brain such
as learning and memory. Two Oreochromis cDNA molecules, fGluR2
α and fGluR2β, containing open reading frames that share 85%
amino acid sequence identities to the rat glutamate receptor
subunit, Glur2. To characterize the gene structure of the
fGluR2β gene, various restriction endonuclease-digested
fragments of the fGluR2β cDNA were used as probes to identify
genomic DNA fragments carrying exons of fGluR2β. The exon-
intron junctions were determined by comparing cDNA and genomic
DNA sequences. To obtain a full length fGluR2β cDNA, 5''-RACE(
rapid amplification of cDNA ends) and 3''- RACE were employed.
The incomplete fGluR2βgene spans more than 55 kb long and
contains at least 17 exons with splice junction donors and
acceptors conforming to the consensus sequences. The
extraordinarily large size of the mouse intron 2 is conserved
in the fGluR2β gene. 3''-alternative splicing is found in the
C-terminal coding region of the fGluR2βgene transcripts. The
gene structures of the fGluR2β and mouse GluR2 are different
in that the fGluR2β gene contains at least one extra intron
present in the region corresponding to the 5''-UTR of the fGluR2
β.
