Schematic diagram of major SINE-derived satellites in squamate genomes. SINE (Squam3, Squam2, and Squam1) structure includes the tRNA-related head with the shaded promoter boxes (orange), body (green), and LINE-derived region (blue); the respective sSat regions are colored the same. Regions marked in gray have neither relation to known sequences nor to each other. The red arrows mark the tandem repeat unit (their numbers varied widely). The original SINE is specified above each panel for a given taxon (on the left). The subscript indices mark the corresponding taxon or species: SRP, Serpentes; Gja, Gekko japonicus; Ppi, Paroedura picta; Ati, Aspidoscelis tigris; Ama, Aspidoscelis marmoratus; Tor, Tretioscincus oriximinensis; and Aca, Anolis carolinensis
