| Data processing |
36 bp raw reads were mapped against NCBI build 37.1 of the mouse genome with ELAND (Illumina).
Uniquely mapped reads were extended to 200 bp and then transformed into the genome-wide reads density (coverage) with the ShortRead Bioconductor package. The coverage from ChIP and IgG control was visualized on a mirror of the UCSC genome browser.
MACS, CCAT, and in-house developed software (unpublished) were used to detect Ldb1 binding peaks.
Identified binding peaks from all software were combined to get the consensus regions. Negative binomial distribution was performed to assign p-value to each consensus region.
Raw reads were mapped with Bowtie10 to mouse NCBI m37 Ensembl transcripts. Count number of reads for each transcript and reads per kb of a transcript per million mapped reads (RPKMs) were calculated and assigned to each transcript.
The longest transcript was chosen as a representative gene for downstream analysis and the highest expression level from alternative transcripts was assigned to the representative gene.
Read counts per representative genes were subjected to DESeq Bioconductor package11 for statistical testing of differentially expressed genes and p-values were adjusted with Benjamini and Hochberg (BH).
Genome_build: mm9
Supplementary_files_format_and_content: tab-delimited identified number of read counts per Ensembl transcript for each sample (count table generated for DESeq pipeline)
