Summary of the occurrence of post-synaptic proteins in the investigated genomes. Yellow fields indicate presence of an orthologue as determined from the corresponding gene tree topology. Letters correspond to the three additional confidence criteria for orthology assignments defined in the Methods section: b, ML bootstrap value >= 70% and/or Bayesian posterior probability >= 0.95; c, congruence between at least two partitions of the same protein or between different domains; d, conservation of domain architecture. Note that Homo and Drosophila have been used as reference taxa for defining the orthology groups.
