UAS regulatory are fused upstream of full-length lncRNA:roX2.
Scer\GAL4da.PU/lncRNA:roX2UAS.cRa is a suppressor of lethal | male phenotype of Df(1)roX2Δ, lncRNA:roX1SMC17A
The lethality of roX1SMC17A;Df(1)roX2Δ double mutant hemizygous males can be rescued by expression of an autosomal insertion of either roX1Scer\UAS.cRa or roX2Scer\UAS.cRa driven by Scer\GAL4da.PU or by combination with either Dp(1;3)DC067 or Dp(1;3)DC511 (autosomal translocations of fragments from the X chromosome containing roX1 or roX2 gene, respectively).
The lethality of roX1SMC17A;Df(1)roX2Δ double mutant hemizygous males is rescued by expression of roX2Scer\UAS.cRa under the expression of Scer\GAL4da.PU.
