| Title |
Dam-comr-1 |
| Sample type |
SRA |
| |
|
| Source name |
adult testes
|
| Organism |
Drosophila melanogaster |
| Characteristics |
genotype: yw
Sex: male
tissue: testes
developmental stage: 2 days old
|
| Growth protocol |
The flies were kept at 23°C
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
25 adult testes were dissected in PBS.
DNA was isolated using phenol-chloroform method. 1ug of genomic DNA was digested by DpnI endonuclease. Digested DNA was ligated with double-stranded DNA adapters and then digested with DpnII endonuclease. Next, methylated fragments were selectively amplified using adapter-specific primer. Before the preparation of libraries for Illumina DamID-seq, the adapters used in DamID procedure were cut with DpnII enzyme. No further fragmentation was performed.

| Data processing |
Sequenced reads were trimmed for adaptor sequence using cutadapt v1.7
The reads obtained were mapped to BDGP R6 Drosophila genome assembly using MOSAIK software with following parameters: -m all -mmp 0.1 -act 20 -a single
For further analysis, only the reads that started with GATC sequence were retained. The number of reads for each genomic fragment between the neighboring GATC sites (GATC fragments) was summed up.
The data were filtered for reproducibility: all GATC fragments were sorted according to the total read count in two biological samples. This list was binned into groups of 200 fragments having similar read counts. For each GATC fragment, a difference in read counts was calculated between the replicates. Those fragments that showed the difference above 2 standard deviations in the particular group were filtered out.
