Plexin cytoplasmic RasGAP domain
This family features the C-terminal regions of various plexins. Plexins are receptors for semaphorins, and plexin signalling is important in path finding and patterning of both neurons and developing blood vessels. The cytoplasmic region, which has been called a SEX domain in some members of this family, is involved in downstream signalling pathways, by interaction with proteins such as Rac1, RhoD, Rnd1 and other plexins. This domain acts as a RasGAP domain.
