Here we provide whole-transcriptome 3'-UTR sequences (UTR3_hg19.fasta) that we scanned for the 26 RBPs listed in Table S2. There are totally 55,935 3'-UTRs in the FASTA file. The total number, 55,935, is a bit smaller than all chromosome-mappable 3'-UTRs (>60,000), due to sequence length requirement (must be >150 and <21000). The PWM files of all 26 RBPs are included in subfolder "pwm." The threshold values we applied on the Specific (for 17 RBPs, Figure 4A) or General (for 9 RBPs, Figure 4B) model prediction scores are provided in file "Threshold.applied.for.binary.classes.txt." Please note that the statistics concerning the 17 Specific models of Table S2 (those void of * annotation) are calculated based on dichomotized Specific prediction results.
The 3'-UTRs confirmed by eCLIP experiments (PMID: 27018577) are given in RBP-Specific FASTA files, under subfolder "eCLIP_supported."
