Figure 1From: Phylogenetically widespread alternative splicing at unusual GYNGYN donorsNomenclature for tandem donor sites and transcripts. (a) Splicing at the downstream e donor makes the upstream GYN exonic while splicing at the upstream i donor makes the complete GYNGYN motif intronic. (b) Simultaneous usage of e or i donor and E or I acceptor results in four different transcripts (e-E, i-E, e-I, and i-I).Back to article page
