Protein
Guanine nucleotide exchange factor DBS
Function
Guanine nucleotide exchange factor that catalyzes guanine nucleotide exchange on RHOA and CDC42, and thereby contributes to the regulation of RHOA and CDC42 signaling pathways (PubMed:17000758, PubMed:11889037, PubMed:12006984). Seems to lack activity with RAC1. Becomes activated and highly tumorigenic by truncation of the N-terminus (By similarity).
Similarity
Belongs to the MCF2 family.
