ras GTPase-Activating Proteins

• 

  Subject Areas on Research

  • A conserved alternative splice in the von Recklinghausen neurofibromatosis (NF1) gene produces two neurofibromin isoforms, both of which have GTPase-activating protein activity. 
  • An essential function for the calcium-promoted Ras inactivator in Fcgamma receptor-mediated phagocytosis. 
  • Cell surface polarization during yeast mating. 
  • Genetic variants at the miR-124 binding site on the cytoskeleton-organizing IQGAP1 gene confer differential predisposition to breast cancer. 
  • Genome-wide association study identifies a sequence variant within the DAB2IP gene conferring susceptibility to abdominal aortic aneurysm. 
  • IQGAP1, a novel vascular endothelial growth factor receptor binding protein, is involved in reactive oxygen species--dependent endothelial migration and proliferation. 
  • Inhibition of Cdc42 during mitotic exit is required for cytokinesis. 
  • Ligation of cell surface-associated glucose-regulated protein 78 by receptor-recognized forms of alpha 2-macroglobulin: activation of p21-activated protein kinase-2-dependent signaling in murine peritoneal macrophages. 
  • RGSZ1, a Gz-selective regulator of G protein signaling whose action is sensitive to the phosphorylation state of Gzalpha. 
  • Ras, superoxide and signal transduction. 
  • SENP3-mediated host defense response contains HBV replication and restores protein synthesis. 
  • Site-specific monoubiquitination activates Ras by impeding GTPase-activating protein function. 
  • The GTPase activating factor for transducin in rod photoreceptors is the complex between RGS9 and type 5 G protein beta subunit. 
  • The NF1 locus encodes a protein functionally related to mammalian GAP and yeast IRA proteins.
