26607390 SAR1A gene silencing in hepatocytes mimics the effect of ethanol: dedimerization of giantin, arresting PDIA3 in the endoplasmic reticulum (ER) and large-scale alterations in Golgi architecture.
24914133 Data indicate that hydroxyurea (HU) induces SAR1 protein expression, which in turn activates gamma-globin expression, predominantly through the Gialpha/JNK/Jun pathway.
24338480 although Sar1A antagonizes the lipoprotein secretion-promoting activity of Sar1B, both isoforms modulate the expression of genes encoding cholesterol biosynthetic enzymes and the synthesis of cholesterol de novo.
23019651 Sedlin bound and promoted efficient cycling of Sar1, a guanosine triphosphatase that can constrict membranes, and thus allowed nascent carriers to grow and incorporate procollagen prefibrils.
22974979 the behavior of the human of Sar1A and Sar1B, a key component of the COPII family of vesicle coat proteins, was examined.
22605651 Sar1 mutant proteins added to metaphase-arrested Xenopus laevis egg extracts cause dramatic effects on membrane organization.
20634891 Observational study of gene-disease association. (HuGE Navigator)
20624903 lipid-directed and tether-assisted Sar1 organization controls membrane constriction to regulate ER export.
20457124 the intracellular trafficking of hCaR from the endoplasmic reticulum is Sar1-dependent via coat protein complex-II vesicles.
19357197 Kir6.2 contains a di-acidic endoplasmic reticulum exit signal, which promotes endoplasmic reticulum exit via a process that requires Sar1.
19135528 Sar 1 H79G mutants efficiently blocked the plasma membrane trafficking of the Kir3.1/Kir3.4 complex however they did not block the Gbeta1gamma2/Kir3.1 interaction.
18318767 Observational study of gene-disease association and pharmacogenomic / toxicogenomic. (HuGE Navigator)
17981133 The Sec31 fragment stimulates GAP activity of Sec23/24, and a convergence of Sec31 and Sec23 residues at the Sar1 GTPase active site explains how GTP hydrolysis is triggered leading to COPII coat disassembly.
