The mutation responsible for the dPob-like phenotype had beenSatoh et al. eLife 2015;4:e06306. DOI: ten.7554/eLife.16 ofResearch articleCell biologyinherited. The recovered flies had been individually digested in 50 l of 200 ng/l Flufenoxuron Autophagy Proteinase K in 10 mM Tris-Cl (pH 8.two), 1 mM EDTA, and 25 mM NaCl at 55 for 1 hr and heat inactivated at 85 for 30 min and at 95 for five min. 0.five l from the digested answer were utilized as the template of PCR amplification for RFLP evaluation according to the technique described within the FlySNP database (Chen et al., 2008; http://flysnp.imp.ac.at/index.php). The mutation responsible for the dPob-like phenotype of 008J was mapped between SNP markers 1417 and 1518 defined within the FlySNP database.Whole-genome and targeted re-sequence of EMS-generated mutantsFor the whole genome re-sequencing from the 008J mutant, the second chromosome was balanced over a balancer, CyO, PDfd-GMR-nvYFP(Bloomington stock number 23230) to facilitate the isolation of homozygous embryo. Working with REPLI-G single cell kit (QIAGEN, Hilden, Germany), the genomic DNA was amplified from two 008J homozygous embryos independently. A sequencing library was ready utilizing Nextera DNA sample preparation kit (Illumina, San Diego, CA, USA) for each embryo and two 250 bp reads were obtained using MiSeq v2 kit (Illumina). Reads had been mapped to release 5 from the Drosophila melanogaster genome utilizing BWA 0.7.5a. The RFLP-mapped region of 008J was covered by reads with an average depth of 23.2and width of 99.five . Mapped reads have been processed applying picard-tools 1.99 and Genome Analysis Tool Kit two.7-2 (GATK, Broad Institute, Cambridge, MA, USA). SNVs and Indels had been named utilizing Haplotypecaller in GATK. SNVs and Indels had been subtracted by the ones from the isogenized starter stock to extract the distinctive variants in 008J and annotated using SnpSift (Cingolani, 2012). The point mutation on 2R:18770005 was verified by capillary sequencing of PCR-amplified fragment making use of 5 GTCGCGGTCACACTTTCTAG three and five CTGCAGCGTCATCAGTTTGT three as primers. For targeted re-sequencing of 655G, a area like CG2943 was amplified from a heterozygous fly of the 655G mutant chromosome and also the starter chromosome making use of KOD FX Neo DNA 74515-25-6 manufacturer polymerase and five TTTTGTTCTTGTTGGGCGACTCCTTTTCCGTCTC three and five AGGCTGTGTCTTTGTTGTTTTGGCGTTGTCGTC 3 as primers. Reads covering the CG2943 gene region at a depth of 2213436 had been obtained applying MiSeq and mapped, as described above. The sequence was confirmed by capillary sequencing and PCR employing five GCAAGAATCC CATCGAGCAT 3 and 5 CCTTCTTCACGTCCCTGAGT 3 as primers.Antisera against dPob and CNX99aFragments of cDNA encoding V28-D104 (dPob-N) or G173-S247 (dPob-C1) of dPob had been amplified from a cDNA clone, LD37839 (Drosophila Genomics Resource Center, Bloomington, IN, USA) and cloned into pDONR-211 employing Gateway BP Clonase II after which into pET-161 expression vector employing Gateway LR Clonase II (Life Technologies, Carlsbad, CA, USA). The fusion proteins with 6xHis-tag had been expressed in BL21-Star (DE3) (Life Technologies) and purified utilizing Ni-NTA Agarose (QIAGEN). To obtain antisera, rabbits were immunized six instances with 300 g dPob-N fusion protein (Operon, Tokyo, Japan) and three rats were immunized six occasions with 125 g dPob-C1 fusion protein (Biogate, Gifu, Japan). Antisera against Drosophila Cnx had been raised by immunizing a rabbit 4 occasions with 400 to 200 g of synthetic peptide corresponding to C-terminal 24 amino acids of Cnx99a protein conjugated to KLH (Sigma Aldrich Japan, Tokyo, Japan).
