Coulson plot representation of the retention/loss of genes encoding trafficking gene complement of the Retromer, Clathrin, ESCRT, AP, and MTC family proteins amongst the 26 species. The fill colors indicate different phyla, for example, red Coulson plots for apicomplexans. Legends at the top of each column denote subunit components of complexes. For each organism, filled sectors of the pie represent presence of the corresponding protein, whereas empty sectors represent a failure to identify the corresponding protein in the genome (the method is described in Appendix 3). In cases where multiple copies of the protein are present, and can confidently be ascribed to unique genes, numbers indicate relevant paralog counts. The 26 species are shown on the left side with a phylogenetic tree. For simplicity, all subunits are listed as per yeast nomenclature, and only revert to human nomenclature when no homologous yeast gene exists. Abbreviations: CHC, Clathrin heavy chain; CLC, Clathrin light chain; V, Vps; C, CHMP; Vt, Vta1; B, Beta, M, Mu; S, Sigma, G, Gamma; A, Alpha; D, Delta; E, Epsilon; Z, Zeta; T20, Tip20; D1, Dsl1; S39, Sec39; T, Trs; T17, Tca17; C, COG; S, Sec; E, Exo; ESCRT, Endosomal Sorting Complex Required for Transport; MCT, multi-subunit tethering complex; AP, Adaptor Protein. IDs of genes encoding the components are listed in Figure 2—source data 2.
