Sos1 Q07889

Full protein name Son of sevenless homolog 1
Gene name SOS1
Species Homo sapiens
Localization N/A
Description Promotes the exchange of Ras-bound GDP by GTP. Probably by promoting Ras activation, regulates phosphorylation of MAP kinase MAPK3 in response to EGF. 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.
