Abstract
We have identified two alternative 5' ends for the GLYT2 glycine transporter in rat brain DNA by using rapid amplification of cDNA ends (RACE) analysis. Study of the genomic DNA revealed that the isoform diversity is generated by alternative use of exons 1a or 1b, respectively. Upon translation, the mRNA corresponding to the novel isoform GLYT2b would yield a protein five amino acids longer than the previously characterized isoform GLYT2a. Both forms display similar regional distribution and kinetics characteristics. However, whereas GLYT2a is able to actively accumulate glycine into transfected COS cells, GLYT2b seems only to exchange (or release) glycine.Entities:
