Unusually large non-linear 1H and 15N nuclear magnetic resonance chemical shifts against pressure have been detected for individual amide groups of the Ras-binding domain of Ral guanine dissociation stimulator (GDS). The non-linear response is largest in the region of the protein remote from the Rap1A-binding site, which increases by about two-fold by the complex formation with its effector pro...
Through chemical screening, we identified a pyrazolone that reversibly blocked the activation of phagocyte oxidase (phox) in human neutrophils in response to tumor necrosis factor (TNF) or formylated peptide. The pyrazolone spared activation of phox by phorbol ester or bacteria, bacterial killing, TNF-induced granule exocytosis and phox assembly, and endothelial transmigration. We traced the py...
Pseudomonas aeruginosa exoenzyme S ADP-ribosylates p21ras and several related proteins. ADP-ribosylation of p21ras does not alter interactions with guanine nucleotides. The ras-related GTP-binding proteins, including Rab3, Rab4, Ral, Rap1A, and Rap2, are also substrates; given these results, we propose a model for the role of exoenzyme S in pathogenesis.
Cohen-Zinder M, Donthu R, Larkin DM, Kumar CG, RodriguezZas SL, Andropolis KE, Oliveira R, Lewin HA. Multisite haplotype on cattle chromosome 3 is associated with quantitative trait locus effects on lactation traits. Physiol Genomics 43: 1185–1197, 2011. First published September 6, 2011; doi:10.1152/physiolgenomics.00253.2010.—The goal of this study was to identify candidate genes and DNA poly...
Ras and Rho small GTPases possessing a C-terminal polybasic region (PBR) are vital signaling proteins whose misregulation can lead to cancer. Signaling by these proteins depends on their ability to bind guanine nucleotides and their prenylation with a geranylgeranyl or farnesyl isoprenoid moiety and subsequent trafficking to cellular membranes. There is little previous evidence that cellular si...
Farnesyl:protein transferase (FPTase) inhibitors were developed as anti-Ras drugs, but they fail to inhibit Ki-Ras activity because Ki-Ras can be modified by geranylgeranyl:protein transferase type-I (GGPTase-I). L-778,123, an inhibitor of FPTase and GGPTase-I, was developed in part because it can completely inhibit Ki-Ras prenylation. To support the clinical development of L-778,123, we develo...
