Hela cells were subjected to SDS PAGE followed by western blot with FNab08118(SOS1 antibody) at dilution of 1:1000
Background
Promotes the exchange of Ras-bound GDP by GTP(PubMed:8493579). Probably by promoting Ras activation, regulates 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).
