Analysis of preferences for alternative splicing and polyadenylation site variation among spliced COPs genes, in dependence of the termination site of the antisense transcript

Spliced COP genes with an antisense transcript not overlapping a sense transcript intron region, show a significant negative bias for alternative splicing
