The boundaries of the TRIM B30.2 domain variable regions are defined as in Song et al. (30). The variable region lengths in amino acid residues are reported, along with those expected of the putative ancestral TRIM protein (Consensus). Variable region lengths greater than those of the consensus are in bold.
