Phylogeny of Voltage-Gated Sodium Channels

A maximum-likelihood tree was constructed using the LG (+F +G +I) model. The bootstrap support out of 100 is indicated at the branches. A Bayesian analysis using the WAG model resulted in identical topology. Posterior probabilities of 1.0 are indicated by a red asterisk, and those of 0.95 < X < 1.0 are indicated by a blue asterisk. All sequences are from cloned cDNA unless otherwise mentioned. Accession numbers and species names are available in Table S1. Animal clades are indicated by colors.
