From: The synapsin gene family in basal chordates: evolutionary perspectives in metazoans
Maximum likelihood phylogeny of synapsins from several vertebrate and invertebrate species. The ML phylogeny of 18 representative synapsin proteins from various model organisms rooted at midpoint is shown. Numbers at nodes indicate the ML and NJ percentage bootstrap support with 1000 replicates (first and second values, respectively). Nodes supported only by the maximum likelihood analysis show a single bootstrap value. The scale bar indicates the number of amino acid substitutions per site.
