Gene Gene information from NCBI Gene database.
Entrez ID 6654
Gene name SOS Ras/Rac guanine nucleotide exchange factor 1
Gene symbol SOS1
Synonyms (NCBI Gene)
GF1GGF1GINGFHGFNS4SOS-1
Chromosome 2
Chromosome location 2p22.1
Summary This gene encodes a protein that is a guanine nucleotide exchange factor for RAS proteins, membrane proteins that bind guanine nucleotides and participate in signal transduction pathways. GTP binding activates and GTP hydrolysis inactivates RAS proteins.

Protein name Son of sevenless homolog 1 (SOS-1)
Protein function Promotes the exchange of Ras-bound GDP by GTP (PubMed:8493579). Probably by promoting Ras activation, regulates phosphorylation of MAP kinase MAPK3/ERK1 in response to EGF (PubMed:17339331). Catalytic component of a trimeric complex that partici
