Shares P-loop motif with GTP_EFTU, arf and myosin_head. See Pfam:PF00009 Pfam:PF00025, Pfam:PF00063. As regards Rab GTPases, these are important regulators of vesicle formation, motility and fusion. They share a fold in common with all Ras GTPases: this is a six-stranded beta-sheet surrounded by five alpha-helices [1].

Plexins are receptors for semaphorins, and plexin signalling is important in path finding and patterning of both neurons and developing blood vessels [1,2]. The cytoplasmic region, which has been called a SEX domain in some members of this family [3], is involved in downstream signalling pathways, by interaction with proteins such as Rac1, RhoD, Rnd1 and other plexins [4]. This domain acts as a RasGAP domain [5].
