Statement
Reference
Imprecise excision of P{EP}caz[EP1564] resulting in a deletion that removes 2443 bp of the caz coding sequence and 3251 bp of the upstream region including the entire caz promoter. The deletion also disrupts CG32576.

Mutants of caz[383] in a CG32576[Scer\UAS.x10] genetic background display defective development. Hemizygous caz[383], CG32576[Scer\UAS.x10]/Y male larvae appear morphologically normal, however, only 14 % of the expected number successfully completed pupariation and eclosed to produce viable adults. caz[T:Zzzz\FLAG] fully rescues the developmental defects seen in hemizygous caz[383], CG32576[Scer\UAS.x10]/Y male larvae. Expression of caz[Scer\UAS.x10.T:Zzzz\FLAG] under the control of Scer\GAL4[elav-C155] restores viability of caz[383] mutants carrying CG32576[Scer\UAS.x10]. Surviving hemizygous caz[383] mutant adults that also carry CG32576[Scer\UAS.x10] have reduced locomotion and longevity. Externally these mutant males display a mild rough eye defect, abnormal genitalia, and defects in both bristles and wing vein organisation, all of which can be rescued by caz[T:Zzzz\FLAG]. The majority of hemizygous caz[383] mutant males carrying CG32576[Scer\UAS.x10] also exhibit defects in locomotion. The majority of the mutants are unable to fly, and compared with controls, they walk slowly, fall over frequently, and have difficulty righting themselves. All of these phenotypes can be rescued by caz[T:Zzzz\FLAG]. Expression of caz[Scer\UAS.x10.T:Zzzz\FLAG] under the control of Scer\GAL4[elav-C155] in caz[383] mutants also carrying CG32576[Scer\UAS.x10] partially suppresses the locomotion defects in the hemizygous males. However, the partially rescued mutants are still significantly slower than controls. Brains of hemizygous caz[383] mutant males that also carry CG32576[Scer\UAS.x10] do not show signs of extensive neuronal loss, for example, vacuolization. Hemizygous caz[383] mutant males that also carry CG32576[Scer\UAS.x10] have shorter life span than control male flies. caz[T:Zzzz\FLAG] fully restores the average life span of these mutants as does neuronal expression of caz[Scer\UAS.x10.T:Zzzz\FLAG] under the control of Scer\GAL4[elav-C155]. The neuromuscular junction (NMJ) morphology of hemizygous caz[383] larvae that also carry CG32576[Scer\UAS.x10] appear normal. The NMJ expansion induced by the overexpression of TBPH[Scer\UAS.10x.T:Avic\GFP-YFP.Venus] under the control of Scer\GAL4[Rapgap1-OK6] is completely suppressed in hemizygous caz[383] larvae that also carry CG32576[Scer\UAS.x10].

Expression of Hsap\FUS[Scer\UAS.10x.T:Zzzz\FLAG] in the nervous system of caz[383] mutant larvae (that also carry CG32576[Scer\UAS.x10]) under the control of Scer\GAL4[elav-C155] restores adult viability. Expression of Hsap\FUS[R522G.10x.Scer\UAS.T:Zzzz\FLAG] in the nervous system of caz[383] mutant larvae (that also carry CG32576[Scer\UAS.x10]) under the control of Scer\GAL4[elav-C155] restores adult viability. Expression of Hsap\FUS[P525L.10x.Scer\UAS.T:Zzzz\FLAG] in the nervous system of caz[383] mutant larvae (that also carry CG32576[Scer\UAS.x10]) under the control of Scer\GAL4[elav-C155] restores adult viability. Expression of Hsap\FUS[Scer\UAS.10x.T:Zzzz\FLAG] under the control of Scer\GAL4[elav-C155] in caz[383] mutants also carrying CG32576[Scer\UAS.x10] partially suppresses the locomotion defects in the hemizygous males. However, the partially rescued mutants are still significantly slower than controls. Expression of Hsap\FUS[R522G.10x.Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[elav-C155] in hemizygous caz[383] mutant males that also carry CG32576[Scer\UAS.x10] does not suppress the caz[383]-associated locomotory defects. Expression of Hsap\FUS[P525L.10x.Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[elav-C155] in caz[383] mutants also carrying CG32576[Scer\UAS.x10] partially suppresses the locomotory defects in the hemizygous males. However, the partially rescued mutants are still significantly slower than controls. Neuronal expression of Hsap\FUS[Scer\UAS.10x.T:Zzzz\FLAG] under the control of Scer\GAL4[elav-C155] fully restores the average life span of caz[383] mutants that also carry CG32576[Scer\UAS.x10]. Neuronal expression of Hsap\FUS[P525L.10x.Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[elav-C155] does not significantly restore median life span in caz[383] mutants that also carry CG32576[Scer\UAS.x10], although maximum life span is increased. Neuronal expression of Hsap\FUS[R522G.10x.Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[elav-C155] does not significantly restore median life span in caz[383] mutants that also carry CG32576[Scer\UAS.x10], although maximum life span is increased.
