From: Differences in polyadenylation site choice between somatic and male germ cells
The poly(A) signal is essential for polyadenylation of male germ cell-specific polyadenylation sites. ATCC 3T3 cells (mouse embryonic fibroblasts) were transfected with reporter plasmids containing the indicated polyadenylation cassettes. Bars represent the average relative luciferase activity over three different replications. Asterisks indicate significant difference from the wild type version of each cassette (p < 0.01).
