GAL4/UAS system [27 (link)] drivers used were btl-GAL4 [44 ], e22c-GAL4 [45 (link)], ppk-GAL4 [32 (link)], and da-GAL4 [24 (link)]. GFP and DsRed transgenes are referenced in Table 1. Df(Smg1)exe2B was generated by using FLP-mediated recombination between the FRTs in P{XP}C3G[d00589] and PBac{WH}CG3044[f02328] as described in Thibault et al. [46 (link)]. Marker mutations and balancer chromosomes are described at http://www.flybase.org. Flies were reared at 25 °C on cornmeal/dextrose medium.
The photoshop mutations were obtained by mutagenesis of an isogenized y w FRT19A chromosome [22 (link)] with 25 mM ethane methyl sulfonate overnight [47 ] in a tracheal mutant screen (to be described elsewhere). The mutations used were on this chromosome unless otherwise noted. To generate homozygous mutant clones, 2- to 6-h-old embryos were collected at 25 °C from a cross of y w * FRT19A/FM7 females to gal80 FRT19A, hsFLP122/Y; btl-GAL4, UAS-GFP males. After a 45-min heat shock at 38 °C to induce FLP expression, embryos were returned to 25 °C to continue development. L3 larvae of genotype y w * FRT19A/gal80 FRT19A, hsFLP122; btl-GAL4, UAS-GFP/+ were identified by GFP mosaicism within the tracheal system and scored for the photoshop phenotype.
The original Smg132AP chromosome (designated 32AP†) carried lethal mutations not associated with the photoshop phenotype. Lethals were removed by crossing 32AP†/y w FRT19A females to w/Y; btl-GAL4, UAS-GFP males and identifying L3 larvae with enhanced GFP throughout their tracheal systems. These Smg132AP/Y; btl-GAL4, UAS-GFP/+ larvae developed into viable adult males. We also found a viable wing morphology mutation on 32AP† that is allelic to wavy. Existing wavy alleles do not show a photoshop phenotype, and the wing phenotype is separable from the photoshop phenotype, so wavy does not seem to contribute to the photoshop phenotype.
The Upf229AA chromosome carries a linked lethal mutation. When recombined away from Upf229AA, the mutation had no effect on tracheal development or reporter expression. However, we have not obtained a recombinant containing Upf229AA without the extraneous mutation.
For complementation tests of Upf2, we used genomic rescue transgenes located on the autosomes to generate males of genotype y w Upf214J v g f FRT19A/Y; P{w+, Upf2+}/+ and crossed these to y w * FRT19A/FM7c females, where the asterisk indicates the tested mutation. Absence of Bar+, white-eyed female progeny indicated failure to complement. For complementation tests of Upf1, we used the Y-linked duplication Dp(1;Y)BSC1, y+, which covers the Upf1 locus. Males of genotype Upf113D/Dp(1;Y)BSC1, y+ were crossed to Upf126A/FM7c females, and the absence of female Bar+ progeny indicated a failure to complement.

Mutations are described at http://flybase.org. Wild type was yellow white or Histone-GFP. All experiments were performed at 25°C unless noted otherwise. cnoR2 was generated by ethane methyl sulfonate on an isogenic FRT82B line. cnoR2 was sequenced by PCR amplifying fragments of the cno coding sequence and sequencing them at the University of North Carolina at Chapel Hill Genome Analysis Facility. Cuticle preparations were made as described previously in Wieschaus and Nüsslein-Volhard (1986) . Unless noted otherwise, fly stocks were obtained from the Bloomington Stock Center. Sources of other stocks are provided in Table S1. cno germline clones were made by heat shocking 48–72-h-old hsFLP1; FRT82BcnoR2/FRT82BovoD1-18 larvae for 3 h at 37°C. arm043A01 and edF72 germline clones were generated similarly.

Flies were cultured on standard medium at 22°C. zydeco (zyd) mutants were generated by ethane methyl sulfonate (EMS) mutagenesis and identified in a screen for temperature-sensitive (TS) behavioral phenotypes (Guan et al., 2005 (link)). zyd1 was mapped to the X heterochromatic region containing CG2893 by recombination and complementation analysis with deficiency chromosomes. Mutation of CG2893 in three independently generated zyd alleles was identified by sequencing and comparison to control genomic sequence. We used the UAS/Gal4 system to drive transgenes in glia. UAS-zyd was constructed by subcloning the zydeco cDNA into pUAST and injected into w1118 by Genetic Services. UAS-myrGCaMP5 was constructed by subcloning the first 90 aa of Src64b, containing a myristoylation target sequence, into pBI-UASc (creating pBI-UASc-myr). GCaMP5G cDNA (Addgene plasmid 31788) was cloned into pBI-UASc-myr and injected using ϕ-C-31 transformation.

Control animals are isogenized (y w ey-FLP GMR-lacZ; FRT80B) unless otherwise indicated. 3L11, 3L12, and 3L13 mutants (y w ey-FLP GMR-lacZ;3L1x FRT80B/TM6B, Tb) were isolated from an ey-FLP ethane methyl sulfonate screen as described previously (Verstreken et al., 2003 (link)) with modifications. cspx1 mutants and UAS-ssp (w;; P{w+UAS-csp-11c/s}, cspu1) flies were provided by K. Zinsmaier (University of Arizona, Tucson, AZ). P-element stocks and deficiencies were obtained from the Bloomington Drosophila Stock Center (Bellen et al., 2004 (link); Parks et al., 2004 (link)), and 3L1 mapping was performed as described previously (Zhai et al., 2003 (link)).
We made a genomic rescue construct by PCR amplifying the 6.5-kb hip14 region from bacterial artificial chromosome clone AC093499. The fragment was cloned into the SalI restriction site of pP{CaSpeR-4} and sequenced. A cDNA construct was made by PCR amplifying hip14 from expressed sequence tag clone LD10758. The fragment was cloned into NotI and XbaI sites of pP{UAST} and sequenced.
To generate genomic GFP-tagged constructs, we first integrated an NheI site just before the ATG start codon (NtermGFP-HIP14) or after the hip14 stop codon (CtermGFP-HIP14) by site-directed mutagenesis (Stratagene). PCR-amplified EGFP sequence was cloned into the NheI site.
We generated chimeric n-SybTMD-CSP constructs by PCR amplifying 111-bp N-terminal and 234-bp C-terminal n-syb sequences from pP{UAST}-syb-GFP and the full-length CSP2 from pP{UAST}-csp2 (provided by K. Zinsmaier). In the next round of PCR, we fused them to generate N-terminal-Syb-csp2-C-terminal-Syb chimeric (SybTMD-csp2). After sequencing, SybTMD-csp2 was cloned into pP{UAST} at NotI and XbaI.
P{w+UAS-SybTMD-csp2} and P{w+UAS-csp2} were expressed using elav-GAL4. For analyses of CSP localization and physiology of third instar larvae, we generated elav-GAL4/+; P{w+UAS-SybTMD-csp2} hip142 FRT80B/Df(3L)brm11 and elav-GAL4/+; hip142 FRT80B P{w+UAS-csp2}/Df(3L)brm11.

CRAC channels were activated by passive Ca2+ store depletion with the Ca2+ chelator 1,2-bis(2-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid (BAPTA) included in the pipette solution. The standard internal solution was composed of 128 mM Cs–aspartate, 10 mM Cs–Hepes, 12 mM BAPTA, and 0.9 mM CaCl2. In some experiments, either 3.2 mM Mg2+ or 30 μM IP3 (Sigma-Aldrich) was added to standard solution. To detect single channel CRAC currents, the concentration of external divalent cations was lowered below 1 μM to enable Na+ to permeate and serve as the charge carrier. The standard external solution contained 145 mM Na-methane sulfonate, 5 mM NaCl, 10 mM N-hydroxyethyl-ethylenediamine-triacetic acid (HEDTA), 10 mM Hepes, and 10 mM d-glucose. For some experiments, Na+ was replaced with N-methyl-d-glucamine (NMDG+). Ca2+ currents were detected in Ca2+-containing solution: 155 mM Na-methane sulfonate, 5 mM NaCl, 2 mM Ca-methane sulfonate, 10 mM Hepes, and 10 mM d-glucose. Aliquots from Ca2+-saturated HEDTA solution were added to standard solution to yield the desired concentration of extracellular free Ca2+ (1, 10, and 50 μM). The pH of all solutions was 7.2, and osmolarity was 300–305 mOsm. The HEDTA stock solution saturated with Ca2+ was prepared using a pH-metric method (Neher 1988). Extracellular solutions and drugs were applied using a gravity-driven perfusion system with output tip diameter of ∼50 μm placed ∼50 μm from the cell. Five barrels were inserted close to the output tip, and solution exchange controlled manually by valves. A complete local solution exchange was achieved within 2 s. For [Ca2+]i imaging, cells were bathed in normal Ringer solution consisting of 155 mM NaCl, 4.5 mM KCl, 1 mM MgCl2, 2 mM CaCl2, 10 mM d-glucose, 5 mM Hepes, pH 7.4. Ca2+-free Ringer solution contained 1 mM EGTA in place of CaCl2 and a total of 3 mM MgCl2. Ca2+ concentration in normal Ringer solution was lowered to 300 μM to reduce the rate of capacitative Ca2+ influx in some measurements. In K+ Ringer, KCl replaced NaCl.
