Deletion within the mrt coding sequence, resulting in a frameshift.
7bp deletion in the mrt coding region leads to a frameshift at codon 453.
Under fed conditions, mrtA-3 mutants present a small but significant decrease in lipid droplet size in the larval fat body, as compared to controls; this phenotype is more sever under starvation conditions.
mrtA-3 is rescued by mrtUAS.Tag:FLAG/Scer\GAL4ppl.PU
