Structure of wild-type canine SILV and sequence of the SINE insertion site in merle dogs. The putative lariat branch point sequence is boxed. Splicing acceptors are indicated by bold type. In merle dogs, the splicing acceptor is located in the 15-bp duplicated sequence (underlined) that flanks the SINE insertion. The average insertion size (not including the duplicated sequence) for the merle dogs analyzed herein is 253 bp.
