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.
Partially edited. Editing is low in embryos and pupae and increases dramatically upon eclosion. Ref.1

Sequence caution

The sequence AAM50022.1 differs from that shown. Reason: Miscellaneous discrepancy. Intron retention.

Alternative products

This entry describes 7 isoforms produced by alternative splicing and alternative initiation. [Align] [Select]

     1-19: MKFDSRVMLNSANNNSPQH → MKFECFSLYCTVLK
Isoform F Ref.1 (identifier: Q9NII1-5)

The sequence of this isoform differs from the canonical sequence as follows:
     1-28: Missing.
Isoform G Ref.1 (identifier: Q9NII1-6)

The sequence of this isoform differs from the canonical sequence as follows:
     1-28: Missing.
     154-191: GIENLSSSKMFEIIQTMLTEKLSNPTSLEQPTFCMSQN → D
