Our SOS1 antibodies have been cited in 31 publications and have 3 product images.

Target Information

Promotes the exchange of Ras-bound GDP by GTP. Probably by promoting Ras activation, regulates phosphorylation of MAP kinase MAPK3 in response to EGF. 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. Expressed in gingival tissues. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.

Alternate Names

GF1; GGF1; GINGF; gingival fibromatosis, hereditary, 1; guanine nucleotide exchange factor; HGF; NS4; Son of sevenless homolog 1; son of sevenless homolog 1 (Drosophila); SOS Ras/Rac guanine nucleotide exchange factor 1; SOS-1; SOS1
