Figure 3From: The mitochondrial uncoupling proteinsSequence alignment of UCP1, UCP2 and UCP3 from human, dog, mouse and rat. Sequences are arranged to demonstrate the tripartite structure and lines between blocks help to identify amino acid residues strictly conserved in the three repeats. In the consensus sequence for each UCP homolog (consen), upper-case letters denote conservation and lower-case letters the existence of similarity.Back to article page
