Adenosine deaminase, RNA-specific, B1

RED1, ADAR2, RNA editing enzyme
This gene encodes the enzyme responsible for pre-mRNA editing of the glutamate receptor subunit B by site-specific deamination of adenosines. Studies in rat found that this enzyme acted on its own pre-mRNA molecules to convert an AA dinucleotide to an AI dinucleotide which resulted in a new splice site. Alternative splicing of this gene results in several transcript variants, some of which have been characterized by the presence or absence of an ALU cassette insert and a short or long C-terminal region.

The molecular link between inefficient GluA2 Q/R site-RNA editing and TDP-43 pathology in motor neurons of sporadic amyotrophic lateral sclerosis patients.
Review
Kwak et al., Japan. In Brain Res, 2014
TAR DNA-binding protein (TDP-43) pathology and reduced expression of adenosine deaminase acting on RNA 2 (ADAR2), which is the RNA editing enzyme responsible for adenosine-to-inosine conversion at the GluA2 glutamine/arginine (Q/R) site, concomitantly occur in the same motor neurons of amyotrophic lateral sclerosis (ALS) patients; this finding suggests a link between these two ALS-specific molecular abnormalities.
