Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nSon of sevenless (SOS) was first identified in as a guanine nucleotide exchange factor (GEF) for Ras acting downstream of the Sevenless receptor (1). Two closely related homologs of SOS are found in mammalian cells: SOS1 and SOS2 (2). SOS1 consists of histone folds, Dbl (DH) and pleckstrin (PH) homology domains, a Ras exchange motif (REM), and Cdc25 homology and polyproline domains (3). SOS1 binds to GRB2, NCK, and other adaptor proteins, and plays an important role in ERK activation downstream of protein tyrosine kinase receptor (RTK). Research studies have identified mutations in the corresponding SOS1 gene of patients with Noonan syndrome, a developmental disorder characterized by short stature, facial dysmorphia, and congenital heart defects (4,5).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nGF1; 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\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M\nSENSITIVITY: Endogenous\nMW (kDa): 152\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46801005215913,"sku":"5890S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-5890s","provider":"Iright","version":"1.0","type":"link"}
