    Detailed Description
    Statement
    Reference

    Diap14 heterozygotes show slight but significant increases in wing size and wing cell numbers, despite of no changes in cell numbers, as compared to controls.

    As in wild type, th1/th4 mutant bursCCAP neurons undergo programmed cell death shortly after eclosion.

    th4 heterozygotes do not exhibit defects in dendrite pruning.

    No retinal phenotypes are seen in th4 mutant flies.

    Mutants heterozygous for th4 exhibit normal scheduled death of Crz-expressing neurons.

    th4 mutant C4da neuron clones exhibit an increase in cell death and die prior to metamorphosis.

    13% of th4/th21-2s egg chambers have border follicle cell migration defects. Homozygous follicle cells clones result in border follicle cell migration defects.

    Diap14 heterozygosity ameliorates the wing defects induced by the expression of InRK1409A.UAS under the control of Scer\GAL4GMR11F02 (decreased wing size and decreases in wing cell size and number).

    The photoreceptor depigmentation phenotype characteristic for adult flies expressing DroncUAS.cSa under the control of Scer\GAL4GMR.PFa is strongly exacerbated by combination with a single copy of Diap14.

    Diap14/+ enhances the late-onset retinal degeneration phenotype of ebi1-334.GMR/+ flies.

    A th4 heterozygous mutant background suppresses the class IV pruning defects seen upon expression of TER94E375Q.E575Q.Scer\UAS under the control of Scer\GAL4ppk.PG. Lowering th levels also sensitises cells to stress-induced apoptosis, and a high proportion of TER94E375Q.E575Q.Scer\UAS-expressing neurons in a th4 heterozygous background undergo apoptosis during early metamorphosis (approximately 60% at 15 hours after pupal formation).

    The semi-lethality seen at 22[o]C in animals expressing scnyGS13668 under the control of Scer\GAL4GMR.PF is enhanced by th4/+, so that none of the double mutant animals eclose.

    th4/+ enhances the severity of the rough eye phenotype caused by expression of scnyGS13668 under the control of Scer\GAL4GMR.PF at 18[o]C.

    A th4 mutant background enhances the moderately rough eye phenotype observed upon expression of mblC.Scer\UAS under the control of Scer\GAL4hs.2sev.

    The addition of th4/+ to egrGS9830, Scer\GAL4GMR.PF animals leads to a completely ablated eye phenotype, an enhancement of the egrGS9830, Scer\GAL4GMR.PF phenotype.

    Addition of this allele strongly enhances the phenotype seen in rprGMR.PW and WGMR.PG flies.
