Scita, Tenca, Frittoli, Tocchetti, Innocenti, Giardina, Di Fiore: Signaling from Ras to Rac and beyond: not just a matter of GEFs. in The EMBO journal 2000
Data show that a heterozygous son of sevenless homolog 1 (SOS1) gene frameshift mutation (c.3266dup or c.3248dup) was identified in each patient.
The present study provides a first evidence of allelic imbalance of SOS1 and pinpoints this condition as a possible mechanism underlying a different penetrance of some SOS1-mutated alleles in unrelated carriers
In non-apoptotic cells, nuclear EGFR (show EGFR Antibodies) induced SOS1 expression by directly binding to the SOS1 promoter.
findings suggest that targeting the Src (show SRC Antibodies)/Abl (show ABL1 Antibodies)/Sos1/Rac (show AKT1 Antibodies) pathway may represent a double-edged sword to control both cancer-invasive capacities and cancer-related inflammation.
These data demonstrated the negative regulation between miR (show MLXIP Antibodies)-146a and SOS1 and between miR (show MLXIP Antibodies)-370 and GADD45beta (show GADD45B Antibodies) and that these regulations are influenced by enterovirus 71 to induce apoptosis.
Combined rational design and a high throughput screening platform for identifying chemical inhibitors of a Ras-activating enzyme.
SOS1 and Ras regulate epithelial tight junction formation in the human airway through EMP1.
HGF (show HGF Antibodies)-related mutation g.126,142-126,143insC in exon 21 was not found in any of the 6 affected individuals from three families.
Stabilized alpha helices of son of sevenless 1 directly inhibit wild-type and mutant forms of KRAS.
CIIA (show VPS28 Antibodies) functions as a negative modulator of the SOS1-Ras signaling events initiated by peptide growth factors including EGF (show EGF Antibodies).
The increased activity of the PI3K/AKT (show AKT1 Antibodies) pathway led to downregulation of the surface receptor CD62L (show SELL Antibodies) in Sos-1/2dKO T cells and a subsequent impairment in T-cell migration.
SUMOylation of Grb2 (show GRB2 Antibodies) enhances the ERK (show EPHB2 Antibodies) activity by increasing its binding with Sos1.
Data suggest that interactions between Sos1 (Son of Sevenless homolog 1) and Crk (show CRK Antibodies) (proto-oncogene (show RAB1A Antibodies) proteins c-crk (show CRK Antibodies)) involve electrostatic interactions at binding sites.
ROS1 (show ROS1 Antibodies) kinase activity and MEK1 (show MAP2K1 Antibodies)/2-ERK1/2 (show MAPK1/3 Antibodies) signaling regulates epithelial differentiation in the epididymis.
Sos1 has distinct roles in acting as a scaffold to oligomerize the adaptor protein LAT (show LAT Antibodies), and in guanine nucleotide exchange activity
ezrin also is important for the activity of SOS itself. Ezrin interacts with GDP-Ras and with the Dbl homology (DH)/pleckstrin homology (PH) domains of SOS, bringing GDP-Ras to the proximity of the allosteric site of SOS.
Absolute counts of mature B and T cells in spleen and peripheral blood were unchanged in single-knockout mutants, while significantly reduced in Sos1/2 double-knockout mice.
Study shows that the ability of Sos1/Grb2 to appropriately regulate pluripotency and differentiation factors and to initiate primitive endoderm development requires collective binding of multiple Sos1/Grb2 domains to their protein and phospholipid ligands.
assessed the independent and combined roles for the RasGEFs Sos1, Sos2 (show SOS2 Antibodies), and RasGRP1 (show RASGRP1 Antibodies) during thymocyte development
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.
