SOS1 SOS Ras/Rac guanine nucleotide exchange factor 1

Gene ID: 6654, updated on 11-Apr-2024
Gene type: protein coding
Also known as: GF1; HGF; NS4; GGF1; GINGF; SOS-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. 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. [provided by RefSeq, Jul 2008]
