General annotation (Comments)
| Function | Has A-to-I RNA editing activity on extended dsRNA: edits RNA-binding protein Rnp4F. A-to-I editing of pre-mRNAs acts predominantly through nervous system targets to affect adult nervous system integrity, function and behavior. Essential for adaptation to environmental stresses, such as oxygen deprivation, and for the prevention of premature neuronal degeneration, through the editing of ion channels as targets. Ref.1 Ref.2 Ref.7 Ref.8 |
| Tissue specificity | Expressed in embryonic nervous system; late stage 13 sees ventral nerve cord expression which spreads to brain by stage 16. Expression is maintained through to adulthood. Ref.1 Ref.2 Ref.7 |
| Developmental stage | Expressed throughout development, highest expression is during pupal stage. Isoforms A, C and D have lowest expression levels. Ref.1 |
| Disruption phenotype | Adult flies are morphologically wild-type but exhibit extreme behavioral defects including temperature-sensitive paralysis, locomotor uncoordination, and tremors which increase in severity with age. Ref.7 |
| Sequence similarities | Contains 1 A to I editase domain. Contains 2 DRBM (double-stranded RNA-binding) domains. |
| RNA editing | Edited at position 437. |
| Sequence caution | The sequence AAM50022.1 differs from that shown. Reason: Miscellaneous discrepancy. Intron retention. |
