The blocks (A–F) are as described in Figure 4. The number of nonredundant accessions per cluster is shown in Table 1. Block A is contained within Calvi's region 1 (Calvi et al. 1991). Blocks B and C correspond to the edges of Calvi's region 2. Blocks D–F are the highly conserved C-terminal region involved in dimerization (Essers et al. 2000).
