Brain-specific over-represented cis elements. (a) Schematic of the four poly(A) regions investigated. (b) Identified cis elements in -100/-41. (c) Identified cis elements in -40/-1. (d) Identified cis elements in +1/+40. Logos are shown for cis elements. Under each logo is the percent of hits for the corresponding cis element in poly(A) sites preferred in brain tissues (red), poly(A) sites not preferred in brain tissues (green), and all poly(A) sites (black). In the graphs, the y-axis is the percent of hits, and the x-axis is the distance to the poly(A) site. Horizontal dotted lines are the average value, and vertical dotted lines are the -100, -40, +40, +100 nt positions.
