CC -!- FUNCTION: Involved in RNA editing. Catalyzes the specific deamination
CC of adenosine-34 in several cytosolic tRNA species. Generates inosine at
CC the wobble position of the anticodon loop.
CC {ECO:0000269|PubMed:25315605}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=adenosine(34) in tRNA + H(+) + H2O = inosine(34) in tRNA +
CC NH4(+); Xref=Rhea:RHEA:43168, Rhea:RHEA-COMP:10373, Rhea:RHEA-

CC Evidence={ECO:0000269|PubMed:25315605};
CC -!- SUBUNIT: Interacts with TAD3. {ECO:0000269|PubMed:25315605}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:25315605}. Cytoplasm
CC {ECO:0000269|PubMed:25315605}. Note=Localizes predominantly to the
CC nucleus. {ECO:0000269|PubMed:25315605}.
CC -!- DISRUPTION PHENOTYPE: Embryonic lethality due to embryo development
CC arrest at the globular stage. {ECO:0000269|PubMed:25315605}.
CC -!- SIMILARITY: Belongs to the cytidine and deoxycytidylate deaminase
CC family. ADAT2 subfamily. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAF79540.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
