The splitting of the family has allowed the related FlaJ_arch (archaeal FlaJ family) to be merged with it. Proteins with this domain in form a platform for the machiney of the Type II secretion system, as well as the Type 4 pili and the archaeal flagella [1]. This domain seems to show some similarity to PF00664 but this may just be due to similarities in the TM helices (personal obs: C Yeats).
