ADARB1
Protein-coding gene in humans
Double-stranded RNA-specific editase 1 is an enzyme that in humans is encoded by the ADARB1 gene. The enzyme is a member of ADAR family.
01Function
This gene encodes the enzyme responsible for pre-mRNA editing of the glutamate receptor subunit B by site-specific deamination of adenosines. Studies in rats 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.
ADARB1 requires the small molecule inositol hexakisphosphate (IP6) for proper function. ADARB1 is an A-to-I RNA-editing enzyme that mostly acts on protein-coding substrates.
