Solution structure of the N-terminal dsRBD of Drosophila ADAR and interaction studies with RNA [PDF]

, 2012
Adenosine deaminases that act on RNA (ADAR) catalyze adenosine to inosine (A-to-I) editing in double-stranded RNA (dsRNA) substrates. Inosine is read as guanosine by the translation machinery; therefore A-to-I editing events in coding sequences may ...

Profound downregulation of the RNA editing enzyme ADAR2 in ALS spinal motor neurons

Neurobiology of Disease, 2012
Amyotrophic lateral sclerosis (ALS) is the most common adult-onset fatal motor neuron disease. In spinal motor neurons of patients with sporadic ALS, normal RNA editing of GluA2, a subunit of the L-α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid ...

ADAR-mediated RNA editing of DNA:RNA hybrids is required for DNA double strand break repair

Nature Communications, 2021
Different roles of specific RNA-related factors in DNA repair have now been reported. Here the authors reveal a role for RNA-editing by ADAR in DNA end resection following double strand break formation and a change in pattern of ADAR2-mediated A-to-I ...

Affect-related behaviors in mice misexpressing the RNA editing enzyme ADAR2 [PDF]

Physiology & Behavior, 2009
Misediting of the serotonin (5HT) 2C receptor (5HT(2C)R) has been implicated in both depression and anxiety. The adenosine deaminases that act on double stranded RNAs (ADARs) are reported to modify the 5HT(2C)R by RNA editing. Transgenic mice misexpressing the RNA editing enzyme ADAR2 show an adult onset obese phenotype due to chronic hyperphagia, but ...

The majority of A-to-I RNA editing is not required for mammalian homeostasis

Genome Biology, 2019
Background Adenosine-to-inosine (A-to-I) RNA editing, mediated by ADAR1 and ADAR2, occurs at tens of thousands to millions of sites across mammalian transcriptomes.

Requirement of the RNA-editing Enzyme ADAR2 for Normal Physiology in Mice [PDF]

Journal of Biological Chemistry, 2011
ADAR2, an RNA editing enzyme that converts specific adenosines to inosines in certain pre-mRNAs, often leading to amino acid substitutions in the encoded proteins, is mainly expressed in brain. Of all ADAR2-mediated edits, a single one in the pre-mRNA of the AMPA receptor subunit GluA2 is essential for survival.

ADAR1 restricts LINE-1 retrotransposition [PDF]

, 2016
Adenosine deaminases acting on RNA (ADARs) are involved in RNA editing that converts adenosines to inosines in double-stranded RNAs. ADAR1 was demonstrated to be functional on different viruses exerting either antiviral or proviral effects.

Core binding factor fusion downregulation of ADAR2 RNA editing contributes to AML leukemogenesis

Blood, 2023
Adenosine to inosine (A-to-I) RNA editing, which is catalyzed by adenosine deaminases acting on RNA (ADAR) family of enzymes ADAR1 and ADAR2, has been shown to contribute to multiple cancers. However, other than chronic myeloid leukemia (CML) blast crisis, relatively little is known about its role in other types of hematological malignancies.

Depletion of the RNA‐Editing Enzyme ADAR1 Invigorates the Antitumor Immunity of NK Cells

Advanced Science, EarlyView.
ADAR1 is upregulated in NK cells from melanoma patients, impairing their function. Its loss enhances NK cell tumor infiltration and cytotoxicity in vitro and in vivo. Mechanistically, ADAR1 deficiency destabilizes CD38 mRNA to reduce its expression, thereby increasing NK cell mobility and killing, which nominates it as a therapeutic target for NK cell ...
