Imprecise excision of the progenitor P{SUPor-P}KG01476 insertion, resulting in a deletion that removes most of IscU.
abnormal oxidative stress response, with IscUS20A
lethal | recessive
lethal - all die before end of larval stage, with IscUS20E
IscU115 homozygotes carrying IscUS20E survive only to the third larval instar stage.
IscU115 flies carrying IscUS20A are more sensitive to oxidative stress (either 10mM paraquat or 2% hydrogen peroxide) compared to controls.
IscU115 is partially rescued by IscUS20A
IscU115 homozygotes carrying IscUS20A are viable and have no visible morphological or developmental abnormalities.
