P{SUPor-P} insertion in the 5' UTR.
A P{SUPor-P} insertion in the first exon of the gb gene.

gbKG07905 flies show both increased susceptibility to S. aureus infection and decreased phagocytosis of S. aureus.
gbKG07905 mutant flies show faster 'bang recovery' than controls: gbKG07905 mutant flies climb the vials approximately three times faster than either wildtype or precise excision controls. This may be because the upward trajectory of gbKG07905 flies is straighter than that of control flies. Accelerated 'bang recovery' is not dependent on age or sex.
Male flies carrying gbKG07905 show frequent homosexual interactions, including singing to other males, genital licking and attempted copulation.
gbKG07905 males presented simultaneously with a wild-type passive (decapitated) male and a wild-type passive (decapitated) virgin female choose to court the male and female with equal intensity and probability (in contrast to wild-type males which always choose to court females). This phenotype is seen both when group and single-pair courtship assays are carried out.
gbKG07905 males show much higher homosexual courtship under dim red light conditions (in which the flies are virtually blind) than control males under the same conditions.
gbKG07905 males show abnormally high courtship levels to mated wild-type females.
Significantly more gbKG07905 males are trapped in an olfactory trap assay using standard food as bait compared to controls.
The neuromuscular junctions of gbKG07905 and gbKG07905/Df(3R)Exel6206 larvae show a large increase in postsynaptic glutamate receptor number. Consistently, the mean amplitude of spontaneous excitatory junction currents (sEJCs) from the L3 muscle 6 NMJ is almost doubled in gbKG07905 and gbKG07905/Df(3R)Exel6206 larvae, but neither mutant shows an increase in sEJC frequency compared with wild-type controls.
gbKG07905 has abnormal courtship behavior | male phenotype, suppressible | partially by mGluR112b
The level of homosexual courtship of gbKG07905 males is reduced to wild-type levels when they are partnered with desat11573-1 males instead of with wild-type males.
The high level of homosexual courtship behaviour that is seen in gbKG07905 males is partially suppressed if they are also mutant for mGluRA112b.
gbKG07905 males react normally to potential partners from other Drosophila species.
Precise excision of the insertion completely rescues the mutant courtship phenotype.
