Figure 4. HnRNP L binding overlaps with polyadenylation signals. Number of hnRNP L crosslink sites around polyadenylation [poly(A)] sites (positions -300 to +300) of protein-coding genes is diagrammed, separately for internal and terminal poly(A) sites (upper and lower panels, respectively). Below, internal (red) and terminal (blue) poly(A) sites are compared, plotted in smooth lines after normalization (lower panel).
