Ral Interacting Protein (Ralbp1): Linking Glutathione Conjugate Transport To Oxidative Stress Defenses And Signaling Pathways
(Chemistry & Biochemistry, 2008-08-08)The glutathione-conjugate transporter protein DNP-SG ATPase was demonstrated to be identical to the independently cloned Ral-effector, Ralbp1. Glutathione-conjugate transport is linked to substrate-stimulated ATPase activity, ... -
Ralbp1 In Stress Resistance
(Chemistry & Biochemistry, 2008-08-08)Ralbp1 is a multi-specific transporter of glutathione conjugates as well as unconjugated amphiphilic toxins. Because glutathione conjugates are major metabolites of toxic lipid peroxidation products generated as a consequence ... -
Redox Active Lipophilic Ruthenium Complexes As Potential Anti-cancer Drugs
The dinuclear ruthenium(II) polypyridyl complexes (RPCs) [(phen)2Ru(tatpp)Ru(phen)2][PF6]4 (P4+) and the monomeric [(phen)2Ru(tatpp)]Cl2 (MP2+) are promising candidates for anti-cancer drug development in terms of the ... -
Redox and Non-Redox Reactions Catalyzed by Biomimetic Flavin-based Organocatalysts and the Discovery of Selective Oxidation Methods for the Preparation of N-Heterocycles
(2018-08-08)In nature, flavoproteins (FMN and FAD) are known to catalyze several chemical transformations which play a vital role in the growth, development, and survival of organisms. They are involved in one-electron and two-electron ... -
RENEWED SIGNIFICANCE OF RAS GTPASES
The Ras superfamily of GTPases act as molecular switches and play a critical role in intracellular signal transduction. These GTPases cycle between an active GTP- bound form and an inactive GDP-bound form to regulate a ... -
RHENIUM(I) COMPLEXES OF TETRAAZATETRAPYRIDOPENTACENE (TATPP): SYNTHESIS, CHARACTERIZATION, REACTIVITY, ANTICANCER POTENTIAL AND LUMINESCENT PROBE TO DETERMINE CELLULAR LOCALIZATION
