Construct: Genomic fragment of 2.8 kb that overlaps the Pros54 gene from the 5' end.
lethal - all die before end of larval stage, with Rpn10Pw+
some die during larval stage, with Rpn10Pw+
Flies that are homozygous for Pros54Pw+ with one copy of Pros54t2.8 are early larval lethals.
Rpn10t2.8 fails to rescue Rpn10Pw+
