The roo sequence is inserted behind codon 84 to cause a premature termination.
neoplasia | adult stage (with matse235), with mats2236.GFP
Occasional matsroo/+ mutant flies are observed to develop tumors.
Some flies expressing mats2236.T:Avic\GFP in a homozygous matsroo mutant background exhibit small tumors.
Some flies expressing mats2236.T:Avic\GFP in a matsroo/matse235 mutant background exhibit small tumors.
When matsroo mutant clones are made, large tumors can be induced in many organs, including the head, notum, eye wing, antenna and halteres. The tumor cells form unpatterned tissues with many folds on the surface, the mutant cells clearly overproliferating. Cell size is not significantly different from wild-type. When clones are made in the larval eye discs, photoreceptors and cone cells appear to be specified normally, however they fail to fully differentiate to generate ommatidia in adults.

matsroo allows recovery of Df(1)su(s)R194/+ clones in the adult eye in animals with mosaic eyes containing two genotypes of cells with respect to RpL36; cells which are Df(1)su(s)R194/+ and cells in which the haplo-insufficiency of Df(1)su(s)R194/+ for RpL36 has been rescued by RpL36+t4 (in a wild-type background the Df(1)su(s)R194/+ clones are eliminated by cell competition and are not seen in the adult eye in these animals). matsroo does not prevent loss of Df(1)su(s)R194/+ clones in the wing disc.

matse17 fails to complement the tissue overgrowth seen in matsroo.
matse17 complements the lethality associated with matsroo.
Expression of mats2236.T:Avic\GFP partially rescues the second instar larval lethality seen in homozygous matsroo mutant flies. 60% of flies survive to the pupal stage and 25% reach the adult stage.
Expression of mats2236.T:Avic\GFP partially rescues the second instar larval lethality seen in homozygous matsroo/matse235 mutant flies. Many flies survive to the pupal stage with some reaching the adult stage.
matsΔ5.T:Avic\GFP is unable to rescue the second instar larval lethality seen in homozygous matsroo mutant flies.
matsΔ3.T:Avic\GFP is unable to rescue the second instar larval lethality seen in homozygous matsroo mutant flies.
