Tre-2/Bub2/Cdc16 domain-containing proteins (TBC proteins) participate in wide range cellular processes. With computational approaches, 137 non-redundant TBC proteins from five model organisms were identified and classified into 13 subfamilies base on molecular evolutionary tree. This phylogenetic analysis provides useful functional annotation of newly-identified TBC proteins and guides for further experimentation.
