Fig. 1. Phylogenetic analysis of Atlantic cod GLUT1. A phylogenetic tree of protein sequences from cod GLUT1 and GLUTs 1-4 from other vertebrates. SwissProt accession numbers are as follows: GLUT1 common carp (AAF75683, GLUT1 rainbow trout (AAF75681, GLUT1 Atlantic cod (AAS17880, (AAB02037, GLUT1 chicken GLUT1 human (AAA52571, GLUT1 rabbit (P13355), GLUT1 cow (P27674), GLUT1 rat (P11167), GLUT1 mouse (AAA37752, GLUT2 chicken (Q90592), GLUT2 rainbow trout (AAK09377, GLUT2 human (AAA59514, GLUT2 mouse (P14246), GLUT2 rat (P12336), GLUT3 cow (AAK70222, GLUT3 dog (P47842), GLUT3 human (AAB61083, GLUT3 mouse (AAH34122, GLUT3 rat (Q07647), GLUT3 chicken (AAA48662, GLUT4 cow (Q27994), GLUT4 human (AAA59189, GLUT4 mouse (P14142), GLUT4 rat (P19357), GLUT4 coho salmon (AAM22227, GLUT4 brown trout (AAG12191, GLUT grass carp (AAP03065, GLUT pacific hagfish (AAL27090. The 28 GLUT protein sequences were aligned using the CLUSTAL W alignment mode in AlignX. The alignment was imported into MEGA version 2.1 and the phylogenetic tree constructed using the neighbor-joining method with Poisson correction. Bootstrap analysis was performed with 1000 replicates. Scale bar shows Tamura Nei distances.
