 Abstract: RNA editing by adenosine deamination in brain-expressed pre-mRNAs for glutamate receptor (GluR) subunits alters gene-specified codons for functionally critical positions, such as the channel's Q/R site. We show by transcript analysis of minigenes transiently expressed in PC-12 cells that, in contrast to GluR-B pre-mRNA, where the two editing sites (Q/R and R/G) require base pairing with nearby intronic editing site complementary sequences (ECSs), editing in GluR5 and GluR6 pre-mRNAs recruits an ECS located as far as 1900 nucleotides distal to the Q/R site. The exon-intron duplex structure of the GluR5 and GluR6 pre-mRNAs appears to be a substrate of double-stranded RNA-specific adenosine deaminase. This enzyme when coexpressed in HEK 293 cells preferentially targets the adenosine of the Q/R site and of an unpaired position in the ECS which is highly edited in brain.
