Gene: SOS1

Alternate names for this Gene: GF1|GGF1|GINGF|HGF|NS4|SOS-1

Gene 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. The product of this gene may regulate RAS proteins by facilitating the exchange of GTP for GDP. Mutations in this gene are associated with gingival fibromatosis 1 and Noonan syndrome type 4.

Gene is located in Chromosome: 2

Location in Chromosome : 2p22.1

Description of this Gene: SOS Ras/Rac guanine nucleotide exchange factor 1

Type of Gene: protein-coding
