An approximately 21kb genomic fragment (the CH322-21M20 BAC clone) containing the entire Patr-1 locus plus approximately 5.4kb of upstream and 10.4kb of downstream DNA.
Two copies of Patr-1+tCH322-21M20 (but not one copy) rescue the lethality of Patr-1d3 homozygotes.
Two copies of Patr-1+tCH322-21M20 significantly suppress the synaptic overgrowth phenotype seen at the muscle 6/7 neuromuscular junction in Patr-1d3 homozygous larvae.
