An Hsp83 promoter drives expression of a deleted form of the lncRNA:roX1 c20 cDNA, which lacks nucleotides corresponding to 3044-3121 of accession number AB051842.
roX1ex6 Df(1)52/Y males carrying P{w+4Δ4.3} generally do not survive to adulthood. This lethality is partly rescued by an autosomal copy of roX1ΔO.Hsp83.
roX1ΔO.Hsp83 partially rescues of the lethality of roX1ex6 Df(1)52, P{w+4Δ4.3} males.
roX1ΔO.Hsp83 partially rescues of the lethality of roX1SMC40A Df(1)52, P{w+4Δ4.3} males.
roX1ΔO.Hsp83 partially rescues of the lethality of roX1ex84A Df(1)52, P{w+4Δ4.3} males.
roX1ΔO.Hsp83 partially rescues of the lethality of roX1SMC17A Df(1)52, P{w+4Δ4.3} males.
