Detailed Description
Statement
Reference

The neuromuscular junctions of Dadj1E4 homozygous transheterozygous third instar larvae present significantly more boutons than controls.

Dadj1E4 mutant third instar larvae show increased number of boutons on neuromuscular junctions, whereas the bouton size is comparable to controls.

Dadj1E4/+ larvae display a slight increase in the fraction of small boutons on the neuromuscular junctions in third instar larvae compared to controls.

Homozygous third instar larvae show an increase in bouton number and satellite bouton number at the neuromuscular junction compared to controls.

The neuromuscular junctions of homozygous larvae show reduced uptake of FM1-43 dye compared to wild type, indicating a defect in endocytosis.

The average number of boutons at the neuromuscular junction is increased in mutant larvae compared to controls.

Homozygous third instar larvae show a significant increase in bouton number/muscle area and satellite bouton number at the neuromuscular junction compared to wild type.

Homozygous and Dadj1E4/Dad271-68 larvae show an increase in both the total number of boutons and the number of satellite boutons at the neuromuscular junction compared to wild type.

Homozygous flies have no discernible mutant wing phenotype.

Homozygotes/hemizygotes have ectopic vein material in the wing.

Heterozygotes show a direct effect on the shape of the wing.

In eggs laid by Dadj1E4/+ females, 3% exhibit short dorsal appendages and ectopic material deposited at the base.

Homozygous and Dad271-68/Dadj1E4 larvae show no significant change in the number of synaptic boutons at the neuromuscular junction.

The synaptic overgrowth phenotype (increased number of boutons at neuromuscular junctions) characteristic for third instar larvae homozygous for Dadj1E4 is completely suppressed by Nlg4KO10 homozygosity and the resulting number of boutons per NMJ is comparable to Nlg4KO10 single mutants and significantly lower than in wild-type controls.

The migration of wing disc cells expressing GliScer\UAS.cSa under the control of Scer\GAL4ap.PU into the non-expressing side of the disc is completely blocked by one copy of Dadj1E4.

dpr11MI02231/Dadj1E4 or DIP-γMI03222/Dadj1E4 transheterozygote third instar larvae have extra satellite boutons at the neuromuscular junction (NMJ) compared to wild type and heterozygotes.

cupΔ212/+;Dadj1E4/+ transheterozygotes show significant increases in satellite boutons at the NMJ of third instar larvae compared to either single heterozygote.

S6KL140/+ ; Dadj1E4/+ transheterozygous mutants exhibit an increase in total bouton number not seen in either heterozygote alone.

Dadj1E4/+ significantly increases synaptic overgrowth of Acsl05847/Acsl8 mutants.

Fmr1Δ50M Dadj1E4 double heterozygous third instar larvae show an increase in bouton number and satellite bouton number at the neuromuscular junction compared to controls.

brat2L-192-9/+ ; Dadj1E4/+ double heterozygotes show a significant increase in the number of satellite boutons at the larval neuromuscular junction compared to wild type.

The increase in bouton number/muscle area and satellite bouton number at the neuromuscular junction which is seen in homozygous Dadj1E4 third instar larvae is not altered if they are also mutant for RhoGAP92B1/RhoGAP92B2.

The decrease in bouton number/muscle area and satellite bouton number at the neuromuscular junction which is seen in third instar RhoGAP92B1/RhoGAP92B2 larvae is significantly suppressed if the larvae are also mutant for Dadj1E4/+.

One copy of Dadj1E4 strongly suppresses the detached posterior crossvein phenotype seen when DysdsRNA.NH2.Scer\UAS is expressed under the control of Scer\GAL4Act.PU but produces extra wing vein material.

One copy of Dadj1E4 strongly suppresses the detached posterior crossvein phenotype seen when DysdsRNA.C.Scer\UAS is expressed under the control of Scer\GAL4tub.PU but produces extra wing vein material.

One copy of Dadj1E4 in a DysE6/+ background results in posterior crossvein defects.

One copy of Dadj1E4 enhances the posterior crossvein phenotype seen when DgdsRNA.Scer\UAS is expressed under the control of Scer\GAL4tub.PU.

Expression of either Dap160Scer\UAS.cKa or nwkScer\UAS.cCa under the control of Scer\GAL4elav-C155 suppresses the increase in the total number of boutons and in the number of satellite boutons at the neuromuscular junction that is seen in homozygous Dadj1E4 larvae.

The severity of the ectopic wing vein phenotype seen in nmoadk1 flies is increased in Dadj1E4 ; nmoadk1 double mutants.

Xenogenetic Interactions
Statement
Reference

The neuromuscular junction growth defects (reduced number of NMJ boutons, decreased NMJ area, length of the longest NMJ branch) as well as larval crawling defects characteristic for third instar larvae expressing Hsap\TARDBPScer\UAS.cHa under the control of Scer\GAL4VGlut.PD can be partially rescued by combination with Dadj1E4 in homozygous state. None of the NMJ growth aberrations can be restored by combination with just single copy of Dadj1E4, except the highly increased fraction of small boutons on the main NMJ axis (which is slightly increased also in Dadj1E4/+ larvae alone).
