Detailed Description

Statement Reference The amplitude of miniature excitatory junctional currents (mEJCs) is normal at the neuromuscular junction (NMJ) in larvae expressing tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[BG380], but the evoked EJC shows an increase in amplitude compared to wild type, resulting in an increase in quantal content at the mutant NMJ. Expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] in the wing discs under the control of Scer\GAL4[T80] leads to ectopic wing vein formation. Expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[A9] results in small wings that are highly pigmented with excess vein tissue. Expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] in the wing with Scer\GAL4[ptc-559.1] induces patterning abnormalities including extensive ectopic vein, fusion of longitudinal veins, and loss of intervein regions. Expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[BG380] does not significantly alter the number of boutons per muscle surface area at the neuromuscular junction of third instar larvae. Expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[elav.PH] in clones induced by FLP/FRT mediated recombination (to activate the Scer\GAL4[elav.PH] driver) results in an increase in the number of type 1b boutons at muscle 13 compared to wild type. Expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[elav.PU] does not affect synaptic growth at the larval neuromuscular junction (the average number of satellite boutons is not significantly different from wild type).
Expression of two copies of tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[elav-C155] results in an increase in both the total number of boutons and the number of satellite boutons at the larval neuromuscular junction. Expression of tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4Mhc.PW results in the ratio of import/export rates being higher than in control muscles (7.4 compared to 3.6). This difference in the import/export ratio explains the net accumulation of nuclear Mad in tkvQ199D.Scer\UAS.T:Ivir\HA1 muscles above the levels of control in steady state. The effective import rate does not increase, but decreases slightly upon constitutive signalling (1.6 times smaller in tkvQ199D.Scer\UAS.T:Ivir\HA1 than in controls), while it is the effective export rate that significantly decreases (3.4 times smaller in
tkvQ199D.Scer\UAS.T:Ivir\HA1).
Constitutive signalling caused by expression of tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4Mhc.PW leads to an increase by an order of magnitude (67%) of the immobile pool of Mad in the nucleus. 100% of wings are overgrown and have numerous ectopic veins in flies expressing tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4A9. Expression of tkvQ199D.Scer\UAS.T:Ivir\HA1 in presynaptic cholinergic neurons, driven by Scer\GAL4B19, is sufficient to produce a large and significant increase in synaptic current amplitude in aCC/RP2 neurons compared to controls. tkvQ199D.Scer\UAS.T:Ivir\HA1 expression in postsynaptic neurons, driven by Scer\GAL4eve.RN2, has no effect on synaptic current amplitude. Expression of tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4elav.PLu or Scer\GAL4OK6 in a wild-type background does not result in a significant increase in the number of neuromuscular junction synaptic boutons. Expression of tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4btl.PS in the tracheal system results in the formation of fine dorsal trunks containing stretches of autocellular adherens junctions. Expression of tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4btl.B123 in single cells or groups of cells in the dorsal trunk results in the formation of ectopic autocellular adherens junctions, although at a low frequency. Expression of tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4A9 causes a wing phenotype. Flies expressing tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4A9 have small wings which are blistered due to lack of adhesion of the dorsal and ventral compartments. Intervein cells express vein-specific hairs and the marginal triple row bristles are transformed into the oversized double row bristles normally seen at more distal positions along the wing margin. The wings are darkly pigmented. | |||

Statement Reference Co-expression of CORL[Scer\UAS.cTa] in the wing disc under the control of Scer\GAL4[T80] suppresses ectopic wing vein formation from CORL[Scer\UAS.cTa] expression. These wings exhibit a few ectopic veins and truncations of L2, L4 and L5 wing veins. Co-expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] dramatically enhances the increase in satellite bouton number at the neuromuscular junction which is seen in larvae expressing Snx16[3A.Scer\UAS.T:Avic\GFP] under the control of Scer\GAL4[elav-C155]. Expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] using the germ cell driver Scer\GAL4[nos.UTR.T:Hsim\VP16] raises the fraction of testes with germline stem cells from 63% to 100% in a magu[e00439]/magu[f02256] background. The median germline stem cell number also doubles compared to that observed in mutants. Co-expression of sax[A.Scer\UAS.cBa] and tkv[Q199D.Scer\UAS.T:Ivir\HA1] in motor neurons under the control of Scer\GAL4[BG380] produces increased mean evoked excitatory junctional potentials (EJPs) and quantal content compared to controls. The size of miniature excitatory junctional potentials (mEJPs) does not differ from controls.
trio[S137203]/trio[6A] suppresses the increase in evoked excitatory junctional potential (EJPs) and quantal content seen when sax[A.Scer\UAS.cBa] and tkv[Q199D.Scer\UAS.T:Ivir\HA1] are expressed in motor neurons under the control of Scer\GAL4[BG380]. The wing patterning phenotypes resulting from the expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] with Scer\GAL4[ptc-559.1] are enhanced by the co-expression of kek5[Scer\UAS.T:Avic\GFP], and there is an additional decrease in wing size. Expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[BG380] significantly suppresses the reduction in the number of boutons per muscle surface area which is seen at the neuromuscular junction in nmo[unspecified] third instar larvae. Expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[elav.PH] in ewg[2] motorneurons (these motorneurons have been obtained by using FLP/FRT mediated recombination to inactivate the ewg[elav.PH] rescuing transgene and simultaneously activate the Scer\GAL4[elav.PH] driver in a ewg[2] background) results in intermediate numbers of boutons at the larval neuromuscular junction compared to wild-type and ewg[2] motorneurons. Expression of tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[elav.PU] enhances the increase in the average number of satellite boutons at the neuromuscular junction that is seen in nwk[2] larvae.
Co-expression of nwk[Scer\UAS.cCa] suppresses the increase in the total number of boutons and in the number of satellite boutons at the neuromuscular junction that is seen in larvae expressing two copies of tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[elav-C155].
Expression of one copy of tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[elav-C155] in a Dap160[Δ1]/+ background results in an increase in both the total number of boutons and the number of satellite boutons at the larval neuromuscular junction compared to wild type.
Co-expression of Dap160[Scer\UAS.cKa] suppresses the increase in the total number of boutons and in the number of satellite boutons at the neuromuscular junction that is seen in larvae expressing two copies of tkv[Q199D.Scer\UAS.T:Ivir\HA1] under the control of Scer\GAL4[elav-C155]. The wing phenotypes caused by expression of tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4A9 are suppressed by co-expression of SnooScer\UAS.cTa; the wing in the co-expressing flies appears similar to the phenotype seen in flies expressing SnooScer\UAS.cTa alone under the control of Scer\GAL4A9. Expression of tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4elav.PLu in a hiwEMS background results in a 30% increase in the number of boutons per muscle surface area at the neuromuscular junction compared to hiwEMS single mutants. The dorsal open phenotype seen in homozygous Cka05836 embryos derived from females carrying homozygous Cka05836 germ-line clones is substantially rescued by expression of tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4hs.PB using heat shock. Scer\GAL4pnr-MD237-mediated expression in Jra76-19 embryos rescues the dorsal open phenotype. Similar dominant wing phenotypes are observed in flies expressing dppScer\UAS.cHa and tkvQ199D.Scer\UAS.T:Ivir\HA1 under the control of Scer\GAL4unspecified that are not observed in flies expressing tkvScer\UAS.cHa under the control of Scer\GAL4unspecified. | |||
