Figure 4. Simplified phylogenetic tree of human UCPs.

Figure 4.

In agreement with the larger tree of Figure 2, we compared protein sequence homologies using the Clustal Omega program (Madeira et al., 2019) give rise to a tree indicating the early divergence of UCP4 and 5 and a later divergence into invertebrate UCPs and a precursor of UCP1, 2 and 3.
