Table 1 The number of hit 3' UTRs and the most frequent common function of the host genes are shown for the each of the most recurrent sequence motifs.

  1. Sequences that overlap the most abundant motif (GUACAUUA) are underlined. The expected average number of hits (standard deviation is in parentheses) is obtained by screening 25 sets of randomly generated DNA sequences, whose length and nucleotide composition are identical tothe 3' UTRs sequences ofthe original dataset. * = estimate based on genes with annotated function
