Table 3 Translation between different connexin nomenclature systems in mammals and teleosts. Some pseudogenes are not included in the overview

From: Phylogeny of teleost connexins reveals highly inconsistent intra- and interspecies use of nomenclature and misassemblies in recent teleost chromosome assemblies

  1. 1There is no official Greek designation for this group, and the predicted genes in mammals have received different names, such as GJA4like, GJD2like or GJC2like (Suppl. Fig. 12). Following our suggestion for the teleosts, the group should be called GJD5 in mammals
  2. 2The human and mouse genes in the CXNK group have not been named consistently in the alphabetic nomenclature. According to our view, the naming in ref. [26] reflects the following orthologous relationships: GJA1 = Cx43 proper = human CXNK2 = mouse cxnk1; human GJA1P = human Cx43P1 = human CXNK1 = no mouse ortholog; human Cx43pX = human GJA6P = no alphabet name in humans = mouse GJA6 = mouse cxnk2
  3. The mammalian Greek nomenclature (first column) is decided by the Human and Mouse Nomenclature Committees. The size nomenclature system in mammals (second column) mentions sizes used in humans and mouse, with exception of the third last row, which shows the size in opossum. The alphabet nomenclature system (third column) was recently suggested by Premzl for eutherian connexins (ref. [26]). Our suggested amended Greek nomenclature for teleosts is shown in bold in the fourth column. The groups with teleost ohnologs are indicated with a/b. The phylogenetic tree with the nomenclatures is shown in Suppl. Fig. 17
