This family features the C-terminal regions of various plexins (e.g. Swiss:P51805). 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].	Domain
