The plasma membrane Na+/H+-antiporter salt overly sensitive1 (SOS1) from the halophytic Arabidopsis-relative Thellungiella halophila (ThSOS1) shows conserved sequence and domain structure with the orthologous genes from Arabidopsis thaliana and other plants. When expression of ThSOS1 was reduced by RNA interference (RNAi), pronounced characteristics of salt-sensitivity were observed. We were in...
BACKGROUND Growth patterns of patients with Noonan syndrome (NS) were established before the involved genes were identified. OBJECTIVE The goal of this study was to compare growth parameters according to genotype in patients with NS. SUBJECTS AND METHODS The study population included 420 patients (176 females and 244 males) harboring mutations in the PTPN11, SOS1, RAF1, or KRAS genes. NS-as...
Inhibition of Ras-stimulating enzymes is a possible avenue to treat Ras-driven diseases. In this issue of Chemistry & Biology, Evelyn and coworkers report an inhibitor for one such enzyme, Sos1, capable of impairing wild-type Ras signaling in cells.
A large genetic screen for sos (for salt overly sensitive) mutants was performed in an attempt to isolate mutations in any gene with an sos phenotype. Our search yielded 28 new alleles of sos1, nine mutant alleles of a newly identified locus, SOS2, and one allele of a third salt tolerance locus, SOS3. The sos2 mutations, which are recessive, were mapped to the lower arm of chromosome V, approxi...
Thymocytes convert graded T cell receptor (TCR) signals into positive selection or deletion, and activation of extracellular signal-related kinase (ERK), p38, and Jun N-terminal protein kinase (JNK) mitogen-activated protein kinases (MAPKs) has been postulated to play a discriminatory role. Two families of Ras guanine nucleotide exchange factors (RasGEFs), SOS and RasGRP, activate Ras and the d...
The SH2 and SH3 domain structural integrity and functionality were confirmed by peptide binding assays. Binding studies using two phosphotyrosine peptides derived from EGFR (FLPVPE{pY}IN-QSVPKR) and Shc (EEPPDHQ{pY}YNDFPGK) for the Grb2 SH2 domain and a SOS1-derived proline-rich peptide (PVPPPVPPRRRPEY) for the SH3 domains were performed using MST 1. Grb2 was fluorescently labeled using Atto488...
سابقه و هدف: سیستم های SOS مهم ترین نقش را در تحمل شوری گیاه دارد. این سیستم در آرابیدوپسیس تالیانا به عنوان یک سیستم پیام رسانی سلول در مسیرهای تحمل به تنش شوری عمل می‌کند. مواد و روش ها: در این تحقیق با بررسی توالی ژن sos1 در آرابیدوبسیس از پایگاه Tair، EBI، NCBI، plantcare وEXPASY و هم چنین جهت بررسی روابط این ژن در سیزده گونه گیاهی مختلف، میزان همولوژی آن ها از لحاظ میزان تشابه با نرم افز...
