TABLE 1.

The members of the Arabidopsis Rab GTPase family

The 57 predicted members are grouped based on C-terminal sequences (-CCXX, -CCXXX, -XCCX, -XCXC, non-cysteine). The members highlighted in boldface type were chosen to test the target specificities of RGTA1·RGTB1, RGTA1·RGTB2, RGTA2·RGTB1, and RGTA2·RGTB2 (Table 2, Fig. 6). The members marked with underline were chosen to represent four types of C-terminal sequences in the cysteine substitution experiments (Fig. 4).
