Son-of-sevenless
WebSon of sevenless homolog 1 (SOS1), a member of the SOS family, is a cohesion protein that plays an important role in the intracellular signal transduction pathways [Citation 15]. Abnormal expression or mutation of SOS1 was found to be associated with a clinical disease [Citation 16]. Webbride of sevenless (boss) and sevenless (sev) genes (4-8). The boss gene product is a transmembrane protein that is localized to the R8 cell (5), and the sevenless gene en-codes a tyrosine kinase receptor expressed on the membranes of many cells in the developing cluster (9, 10).

WebActivation of the small guanosine triphosphatase H-Ras by the exchange factor Son of Sevenless (SOS) is an important hub for signal transduction. Multiple layers of regulation, through protein and membrane interactions, govern activity of SOS. We characterized the specific activity of individual SOS molecules catalyzing nucleotide exchange in H ... WebSon of sevenless homolog 1 is a protein that in humans is encoded by the SOS1 gene. FYVE, RhoGEF and PH domain-containing protein 1 (FGD1) also known as faciogenital dysplasia 1 protein (FGDY), zinc finger FYVE domain-containing protein 3 (ZFYVE3), or Rho/Rac guanine nucleotide exchange factor FGD1 is a protein that in humans is encoded by the FGD1 …
WebActivation of the sevenless protein-tyrosine kinase is required for the proper specification of R7 photoreceptors in the Drosophila eye. The activation of a Ras protein, p21Ras1, is a crucial early event in the signaling pathway, and constitutive activation of p21Ras1 is sufficient to induce all of the effects of sevenless action. In cell signalling, Son of Sevenless (SOS) refers to a set of genes encoding guanine nucleotide exchange factors that act on the Ras subfamily of small GTPases. See more The gene was so named because the Sos protein that it encoded was found to operate downstream of the sevenless gene in Drosophila melanogaster in a Ras/MAP kinase pathway. When sevenless is mutated or … See more Ras-GTPases act as molecular switches that bind to downstream effectors, such as the protein kinase c-Raf, and localise them to the membrane, resulting in their activation. Ras-GTPases are considered inactive when bound to guanosine diphosphate (GDP), … See more Dominant mutant alleles of SOS1 have recently been found to cause Noonan syndrome and hereditary gingival fibromatosis type 1. … See more • SOS1+Protein at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • ExPASy Proteomics Server: SOS See more
