Fig. 2From: Cis regulatory motifs and antisense transcriptional control in the apicomplexan Theileria parva Distribution of the TYAYWWW motif around transcription initiation sites. The horizontal axis represents sequence areas from -1,000Â bp to +1,000Â bp around transcription initiation sites with single nucleotide resolution. Position 0 represents the transcription initiation site, with a peak observed at the -3 position. The vertical axis represents the normalized frequency of the motifBack to article page
