  • Number of motif hits and frequency in the human and mouse unigene databases, as well as the experimental data set. For each transcript region (5′ UTR, CR, and 3′ UTR), the total number of motif hits, as well as the frequency (hits per kb), are shown. Data are provided for the HuR motif meeting three different score thresholds (>0, >1, and >3).
