Comparison of consensus sequences of four HAmo SINE subfamilies, type I, II, III and IV. The tRNA-derived region of three SINE families and the tRNAlys (CUU) in rabbit are aligned. The different family-specific regions represented the most diagnostic nucleotides. The tail regions of these SINEs and their partner LINEs tail are compared. When most of nucleotides at a given position are identical, they are shaded. The GenBank accession numbers of novel HAmo LINE2 sequences are as follows: GQ370975-GQ370988.
