FlyBase curator comment: Co-expression of saxK262H.UAS.Tag:FLAG and gbbUAS.cKa are required to induce constitutive BMP signalling equivalent to that induced by expression of Hsap\ACVR1R206H.UAS.Tag:FLAG alone.
The expression of gbbUAS.cKa under the control of Scer\GAL4A58 does not lead to any obvious third instar larval C4da neuron morphology defects, as compared to controls.
Over expression of gbbScer\UAS.cKa, under the control of Scer\GAL4twi.PG results in a relatively minor but statistically significant reduction in the total number of germ cells.
Expression of gbbScer\UAS.cKa under the control of Scer\GAL4how-24B results in a neuromuscular junction overgrowth phenotype.
Expression of gbbScer\UAS.cKa under the control of Scer\GAL4en.PU from the onset of pupal development (the temperature sensitive allele Scer\GAL80ts.αTub84B is used to restrict the stage during which expression occurs) results in wing defects which are more prominent in the posterior half.
Expression of gbbScer\UAS.cKa under the control of Scer\GAL4A9 results in a variable wing phenotype, marked by ectopic vein material.
Larvae expressing gbbScer\UAS.cKa under the control of Scer\GAL4D42 display a 40% increase in the number of boutons at neuromuscular junction (NMJ) 6/7 and a 62% increase in type I boutons at NMJ 4. Scer\GAL4OK6-mediated expression of gbbScer\UAS.cKa has a comparable effect.
Overexpression of gbbScer\UAS.cKa using Scer\GAL4A9 results in a severe wing blistering phenotype in 79% of females and a more severe phenotype, including unfurling and blistering of the wing in 93% of males.
Expression of gbbScer\UAS.cKa under the control of Scer\GAL4ptc-559.1 results in an ectopic wing vein phenotype.
Expression of gbbScer\UAS.cKa in the wing with Scer\GAL4ptc-559.1 induces an expanded region of ectopic vein where the anterior crossvein would normally form.
Overexpression of gbbScer\UAS.cKa post-synaptically under the control of Scer\GAL4eve.RN2 increases synaptic current amplitude compared to controls.
Expression of gbbScer\UAS.cKa in the wing disc at 25oC, under the control of Scer\GAL4A9, produces wings divided into four classes of phenotypic severity according to the amount of extra wing vein material present in the wing.
The proximal 25% of the anterior margin of a gbbScer\UAS.cKa/Scer\GAL4ap-md544 wing has no bristles. More distally, the triple row reappears but is quite irregular. When gbbScer\UAS.cKa is driven in all the cells of the wing blade with Scer\GAL4C-765, the phenotype is similar but less severe.
Overexpression of gbbScer\UAS.cKa, under the regulation of Scer\GAL4A9, can result in wing disruption.
Postsynaptic expression of gbbUAS.cKa, under the control of Scer\GAL4eve.RN2, results in the averaged amplitude of synaptic currents recorded from whole-cell voltage clamp recordings of aCC/RP2 motoneurons being significantly increased compared with controls. In contrast, expression of gbbUAS.cKa in presynaptic cholinergic interneurons, driven by Scer\GAL4ChAT.7.4, does not affect the averaged synaptic current amplitude.
gbbScer\UAS.cKa; Scer\GAL4C587 females do not have increased numbers of germ-line stem cells in their germaria.
Expression of gbbScer\UAS.cKa under the control of Scer\GAL4A9 produces slightly broadened wings consisting of solid veins.
Expression of gbbScer\UAS.cKa under the control of Scer\GAL4dpp.blk1 does not produce a mutant phenotype. Expression of gbbScer\UAS.cKa under the control of Scer\GAL4en-e16E results in overgrowth of the wing disc and defects restricted to the posterior compartment of the wing.
Flies expressing gbbScer\UAS.cKa under the control of Scer\GAL4ptc-559.1 show ectopic vein material anterior to the anterior/posterior boundary in the wing, associated with a decrease in intervein tissue between veins L3 and L4. Flies expressing gbbScer\UAS.cKa under the control of Scer\GAL471B have wing blisters and ectopic vein material. Flies expressing gbbScer\UAS.cKa under the control of Scer\GAL4A9 show excessive vein formation in the wing.

The ability of gbbScer\UAS.cKa expressed under the control of Scer\GAL4Toll-6-D42 to rescue the electrophysiological defects seen at the neuromuscular junction in gbb1/gbb2 larvae is impaired but not completely abolished if the larvae are also homozygous for cmpyΔ8.
Expression of gbbScer\UAS.cKa under the control of either Scer\GAL4elav.PLu or Scer\GAL4G14 does not suppress the reduction in NMJ bouton number seen in Neto109 mutant larvae.
The severity of the wing phenotype caused by expression of gbbScer\UAS.cKa under the control of Scer\GAL4A9 is reduced by co-expression of saxScer\UAS.T:Zzzz\FLAG.
Co-expression of cmpyScer\UAS.cJa suppresses the neuromuscular overgrowth phenotype caused by expression of gbbScer\UAS.cKa using either Scer\GAL4D42 or Scer\GAL4OK6.
Co-expression of cmpyScer\UAS.cJa suppresses the wing blistering phenotype caused by Scer\GAL4A9-mediated expression of gbbScer\UAS.cKa in males and females.
Mesodermal expression of gbbScer\UAS.cKa (under the control of Scer\GAL4how-24B) suppresses the phenotype observed with fracScer\UAS.cMa over-expression (48% to 28%).
Co-expression of either sogScer\UAS.cYa or Hip14Scer\UAS.cKa suppresses the ectopic wing vein phenotype caused by expression of gbbScer\UAS.cKa under the control of Scer\GAL4ptc-559.1.
Overexression of gbbScer\UAS.cKa with Ppt1Scer\UAS.cKa, both under the control of Scer\GAL4GMR.PF suppresses the visual system degeneration seen upon Ppt1Scer\UAS.cKa expression alone.
The ectopic vein phenotype in the area where the anterior crossvein normally forms resulting from the Scer\GAL4ptc-559.1 driven expression of gbbScer\UAS.cKa can be suppressed by co-expressing kek5Scer\UAS.T:Avic\GFP in the wing.
The ectopic vein phenotype in the area where the anterior crossvein normally forms resulting from the Scer\GAL4ptc-559.1 driven expression of gbbScer\UAS.cKa is not influenced by co-expressing kek4Scer\UAS.T:Avic\GFP in the wing.
Overexpression of gbbScer\UAS.cKa post-synaptically under the control of Scer\GAL4eve.RN2 fails to suppress the reduced synaptic currents found in Chats2 mutant second instar larvae raised at 18[o]C.
Expression of cv-2Scer\UAS.cSa suppresses the wing phenotypes seen when gbbScer\UAS.cKa is expressed under the control of Scer\GAL4A9.
Coexpression of gbbScer\UAS.cKa in the wing disc with saxScer\UAS.T:Ivir\HA1, under the control of Scer\GAL4A9, results in an enhancement of the Scer\GAL4A9>gbbScer\UAS.cKa wing vein phenotype; all wings show the mildest form of vein phenotype in the gbbScer\UAS.cKa-saxScer\UAS.T:Ivir\HA1 coexpressing wings, while less than 10% of wings show this mild phenotype in gbbScer\UAS.cKa wings.
Expression of gbbScer\UAS.cKa, under the control of Scer\GAL4A9, in a sax4/+ background partially suppresses the extra wing vein phenotype; over 90% of flies expressing both UAS transgenes show the most severe form of the Scer\GAL4A9>gbbScer\UAS.cKa phenotype, compared to about 20% of Scer\GAL4A9>gbbScer\UAS.cKa flies.
Coexpression of tkvScer\UAS.T:Ivir\HA1 and gbbScer\UAS.cKa enhances the Scer\GAL4A9>gbbScer\UAS.cKa wing vein phenotype so that a higher percentage of wings have extensive amounts of wing vein tissue.
Expression of gbbScer\UAS.cKa, under the control of Scer\GAL4A9, in a tkv7/+ background suppresses the extra wing vein phenotype of Scer\GAL4A9>gbbScer\UAS.cKa flies. Around 80% of Scer\GAL4A9>gbbScer\UAS.cKa; tkv7/+ wings show a very mild vein phenotype, while around 20% appear wild type.
Co-expression of cvScer\UAS.cVa with gbbScer\UAS.cKa, under the regulation of Scer\GAL4A9 has no detectable effect on the overexpression phenotype of gbbScer\UAS.cKa (wing disruption). Co-expression of cvScer\UAS.cVa and sogScer\UAS.cYa, with gbbScer\UAS.cKa, under the regulation of Scer\GAL4A9 re-establishes the intervein tissue and the longitudinal veins with a series of expanded crossveins between L2 and L3 on the wing. Therefore, cv and sog interact together to suppress the wing phenotype of gbb. Co-expression of tsgScer\UAS.cYa and sogScer\UAS.cYa, along with gbbScer\UAS.cKa, under the regulation of Scer\GAL4A9 partially suppresses the excess gbbScer\UAS.cKa wing disruption phenotype. Co-expression of tsgScer\UAS.cYa and gbbScer\UAS.cKa, under the regulation of Scer\GAL4A9 suppresses the excess gbb phenotype.
Postsynaptic expression of gbbScer\UAS.cKa, under the control of Scer\GAL4eve.RN2, fails to potentiate synaptic current amplitude in aCC/RP2 neurons when expressed in a Chats2 homozygous background at 29oC, compared to in a Chats2/+ control background. If larvae are allowed to recover at 20oC for another 22 hours, the ability of gbbScer\UAS.cKa to potentiate synaptic current amplitude in a Chats2 background is restored.
The solid vein phenotype caused by expression of gbbScer\UAS.cKa under the control of Scer\GAL4A9 is strongly suppressed by co-expression of sogScer\UAS.cYa or of sogsupersog1.Scer\UAS.
Flies expressing gbbScer\UAS.cKa under the control of Scer\GAL4A9 at 25oC have slightly larger wings than normal with minor venation defects along veins L2 and L5. Flies expressing gbbScer\UAS.cKa under the control of Scer\GAL4A9 at 30oC have blistered and highly pigmented wings. The wing phenotype caused by expression of gbbScer\UAS.cKa under the control of Scer\GAL4A9 is partially suppressed if the flies are also coexpressing tkv1ΔGSK.Scer\UAS, and is almost completely suppressed if the flies are also coexpressing saxΔI.Scer\UAS.
The wing phenotype caused by expression of gbbScer\UAS.cKa under the control of Scer\GAL4A9 is suppressed by co-expression of Hsap\ACVR1Scer\UAS.T:Zzzz\FLAG and the resulting flies have a reduction in wing size and a loss of wing vein material.
The solid vein phenotype caused by expression of gbbScer\UAS.cKa under the control of Scer\GAL4A9 is not suppressed by co-expression of Xlae\nogginScer\UAS.cYa.

gbbUAS.cKa/Scer\GAL4hs.PB partially rescues gbb4/gbb1
Expression of gbbScer\UAS.cKa under the control of Scer\GAL4Toll-6-D42 rescues the reduction in spontaneous miniature excitatory junction potential frequency, evoked excitatory junction potential amplitude and quantal content which is seen at the neuromuscular junction in gbb1/gbb2 larvae.
The phenotypes associated with homozygous gbb1 mutants (including lethality, larval transparency and abnormal fatty acid uptake and transport to the fat body) are rescued by expression of gbbScer\UAS.cKa driven by Scer\GAL4fat.
The presence of P{UAS-gbb.K}9.9 alone (in the absence of any driver) can rescue survival of gbb1/gbb2 animals to 3rd instar or pupal stage. The additional presence of Scer\GAL4G14 rescues bouton density and spontaneous mini-EJP (excitatory junctional potential) frequency to wild-type levels, and partially rescues spontaneous mini-EJP amplitude, evoked EJP frequency and levels of neurotransmitter release at synapses. Essentially identical results are seen when Scer\GAL4BG380 is used instead (although bouton density not measured). However, when Scer\GAL4elav-C155 is used there is only a slight rescue of bouton density, but the frequency and amplitude of spontaneous mini-EJPs, the amplitude of evoked EJPs and the levels of neurotransmitter release at synapses are all rescued to wild-type levels.
The testis defects seen in gbb4 homozygous males are rescued by expression of gbbScer\UAS.cKa under the control of Scer\GAL4nos.UTR.T:Hsim\VP16.
