Description Ribosome profiling, mRNA-Seq, RIP-Seq, and Bind-n-SeqRibosome profiling for sample 1-5, and 11-15. Sample1 and 2 are replicates of control of DMSO treatment for sample 3-5, and 11, with RocA and PP242 treatments. Sample 12 and 13 are replicates of control of DMSO treatment for sample 14 and 15 with Hipp treatments.mRNA-Seq for sample 6-10. Sample 6 and 7 are replicates of control of DMSO treatment for sample 8-10 with RocA treatments.RIP-Seq for 16-19. Sample 16 and 17 are replicates of control of DMSO treatment for sample 18-19 with RocA treatments.Bind-n-Seq for 20-23. Sample 21 is control of DMSO treatment for sample 22-23 with RocA treatments. Sample 20 is a input contol for protein-bound fraction of sample 21.We stably expressed SBP (streptavidin binding peptide)-tagged eIF4A in HEK 293T-REx cells and purified it via M270 streptavidin beads (life techonologies). MethodsRaw sequence data were obtained from NCBI FTP directory(SRP059825). Data from the following samples were processed:
RocA_3_uM | Ribosome profiling data from Homo sapiens(Iwasaki, et al. 2016) |
RocA_0 | Ribosome profiling data from Homo sapiens(Iwasaki, et al. 2016) |
Hipp_1_uM | Ribosome profiling data from Homo sapiens(Iwasaki, et al. 2016) |
Hipp_0 | Ribosome profiling data from Homo sapiens(Iwasaki, et al. 2016) |
PP242_2 | Ribosome profiling data from Homo sapiens(Iwasaki, et al. 2016) |
DMSO | Ribosome profiling data from Homo sapiens(Iwasaki, et al. 2016) |
HEK_293_T-REx_cell | Ribosome profiling data from Homo sapiens(Iwasaki, et al. 2016) |
RocA_0 | Ribosome profiling data from Homo sapiens(Iwasaki, et al. 2016) |
Adapter sequence CTGTAGGCACCATCAAT was removed from reads using Cutadapt An alignment to ribosomal RNA was performed using Bowtie, and aligning reads were discarded. An alignment to the hg38 genome assembly was performed using Bowtie, and these tracks contains the uniquely mapping reads.An offset of 15 nucleotides was then used to get the corresponding A-site of each read.
