(b) 3’ end alignment of the U2 spacer; 3’b: 3’ Box; D: Putative DSE element; RE: Regulator Element; P: PSE element. (c) 5' end alignment of the U2 spacer; Hdi: Halobatrachus didactylus; Dla: Dicentrarchus labrax; Dpu: Dicentrarchus punctatus. (d) Alignment of the DSE element with those obtained from other species.
