Genetic Innovation in Vertebrates: Gypsy Integrase Genes and Other Genes Derived from Transposable Elements

Figure 1

Molecular phylogeny of GIN proteins. Phylogenetic tree based on a 352 amino-acid integrase alignment. Protein sequences were aligned with clustalW and phylogenetic tree was constructed using maximum likelihood from PhyML package (optimized default bootstrap) [65]. Sequences were recovered from NCBI and Ensembl or predicted from genome sequences. Accession numbers and sequence alignments are available upon request.
