UASt regulatory sequences drive expression of bor, mutated to carry a L83V amino acid substitution. This change is equivalent to a L77V change in the orthologous human ATAD3A gene, an SNV identified in individuals with neurological and mitochondrial phenotypes. The coding sequence is tagged with Tag:V5.

L83V
Analogous mutation in human ATAD3A implicated in Harel-Yoon syndrome; mutation carried on in vitro construct.
borT2A-Gal4/borc05496 adults expressing either borL83V.UAS.Tag:V5 or borR176W.UAS.Tag:V5 under the control of Scer\GAL4bor-T2A-Gal4 (the intrinsic driver of borT2A-Gal4) are short lived and show a progressive decrease in climbing activity and flight ability; thorax muscles exhibit mitochondria of aberrant size, with cristae defects, and increased autophagic intermediates.
Scer\GAL4bor-T2A-Gal4, borUAS.Tag:V5, borL83V.UAS.Tag:V5 partially rescues borT2A-Gal4/borc05496
