Promotes the exchange of Ras-bound GDP by GTP (PubMed:8493579).
Probably by promoting Ras activation, modulates phosphorylation of MAP kinase MAPK3 in response to EGF (PubMed:17339331).Catalytic component of a trimeric complex that participates in transduction of signals from Ras to Rac by promoting the Rac-specific guanine nucleotide exchange factor (GEF) activity (By similarity). .
