Vav proteins
Vav proteins are GTP exchange factors for Rho GTPases . As a result, they act in the signal line of cells. There are three different Vav proteins in mammalian cells. While Vav-1 on hematopoietic cells is restricted, Vav-2 and Vav-3 are in different cell types expressed . All three contain a DH (Dbl-homology) domain, which catalyzes the GTP exchange in small Rho GTPases, a PH (pleckstrin-homology) domain and an SH2 domain which is bordered by two SH3 domains.
