From: Genomic characterization of the European sea bass Dicentrarchus labrax reveals the presence of a novel uncoupling protein (UCP) gene family member in the teleost fish lineage

Figure 7

Evolutionary scenario that produced vertebrate UCP genes. The major evolutionary events (i.e. duplication and speciation) are highlighted in colors. The symbol (X) indicates genes that have been lost. Thus, UCP1 has been lost in reptile and bird lineages after the first duplication whereas UCP2 and UCP3 have respectively been lost in birds and amphibians after the second duplication. After the third duplication, C2CD3 was lost by the original fragment whereas all genes comprised between CAMKK1 and UCP3 including UCP2 were lost by the duplicated fragment. DL: Dicentrarchus labrax; GA: Gasterosteus aculeatus; OL: Oryzias latipes; TN: Tetraodon nigroviridis; TR: Takifugu rubripes; DR: Danio rerio.
