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.
