A computational analysis indicates that agnathans [jawless fishes] have the potential to generate from 1014 to 1017 different variable lymphocyte receptor (VLR) genes through a process of somatic rearrangement, a level of diversity comparable to that of mammalian antibodies.

N.M. Alto et al., "Identification of a bacterial type III Effector family with G protein mimicry functions," Cell, 124:133-45, Jan 13 2006.
This study reports that type III effectors sharing a WxxxE motif act as Rho GTPase functional mimics. Although none of these effectors show sequence homology with GTPases, the EPEC Map protein induces Cdc42-like actin rearrangements, whereas the Shigella IpgB1 and IpgB2 effectors act as the Rac and the Rho GTPases, respectively.
