FlyBase curator comment: this entry is used to capture phenotypic information when the particular allele (or allele combination) used by the author could not be determined but the context of the experiment suggests that the phenotype being described is some kind of loss of function.
Mutant adults have severe mitochondrial morphology defects in the indirect flight muscles (IFMs); 84% lack lamellar cristae, while 7% are enlarged and highly aberrant. The myofibrils of the IFMs appear similar to wild type.
Vap33unspecified is rescued by Vap33UAS.cPa/Scer\GAL4C164
Expression of Vap-33AScer\UAS.cPa under the control of Scer\GAL4C164 rescues nearly 100% of the indirect flight muscle mitochondrial defects seen in Vap-33Aunspecified adults.
