The DPP sequences of 26 mammalian species and green anole. Specific motifs are highlighted: SSD-like (highlighted in grey and includes a few simple variations on the tripeptide motif such as SSN and SSE); SKSD-like (blue); RGD (yellow); SSSSS (green); and dipeptides (pink). The extended carboxy-terminal regions for platypus and anole are highlighted in red. Within the anole sequence, serines encoded by TCN-type codons within the repeat domain are in black bold and arginines are highlighted in blue. All serines within the mammalian SSD repeat (except for SKSD) are AGC/T type codons. Stop codons are noted as *. A larger font file of these sequences is available as Additional File 3.
