Disease relevance of AIDS-129097

• The IF(1)-IF(1), gamma-IF(1), and alpha-IF(1) cross-linkages previously formed with dithiobis(succinimidylpropionate) in bovine F(1)F(0)I and IF(1) complexes were reproduced in the F(1)F(0)I-ATP synthase of hepatoma AS-30D cells [1].
• [125I]Monoiodinated vasoactive intestinal peptide (125I-VIP) was cross-linked with human colonic adenocarcinoma cells (HT29 cells) grown as a monolayer using dithiobis(succinimidylpropionate) as cross-linking reagent [2].
• Proteins that were closely associated with murein in intact cells of Escherichia coli were studied by treating [3H]leucine and [3H]palmitate-labeled cells with the chemical crosslinking reagent dithiobis(succinimidylpropionate) [3].

• DAD1 can be crosslinked to OST48 in intact microsomes with dithiobis(succinimidylpropionate) [4].

Biological context of AIDS-129097

• The present study has made use of a covalent cross-linking agent, dithiobis(succinimidylpropionate), to study the self-association of prothrombin fragment 1 and has focused on factors influencing the covalent dimerization of bovine prothrombin fragment 1 during reaction with this reagent [9].
• To identify the molecular components of the vasoactive intestinal peptide (VIP) binding sites in the liver, 125I-labelled VIP was covalently linked to liver membranes by using the cleavable cross-linker dithiobis(succinimidylpropionate) [10].
• Finally, dithiobis(succinimidylpropionate) cross-linking was used to confirm that Wzc(CPS) forms complexes in vivo, independent of the phosphorylation state of the protein [11].
• In the present study, we have identified and characterized an SP-A cell surface binding protein by utilizing two chemical cross-linkers: profound sulfo-SBED protein-protein interaction reagent and dithiobis(succinimidylpropionate) (DSP) [12].
• In contrast, exposure to 1 mM DSP for 15 min led to severely limited cell viability and phenotypic expression probably due to the increased crosslinking time [13].

Anatomical context of AIDS-129097

• Most of the cellular functions inhibited through the reaction of neutrophils with the cleavable cross-linker dithiobis(succinimidylpropionate) could be restored by reduction of the disulfide bonds of the cell-bound cross-linker with dithiothreitol [14].
• The location of the endogenous inhibitor protein (IF1) in the rotor/stator architecture of the bovine mitochondrial ATP synthase was studied by reversible cross-linking with dithiobis(succinimidylpropionate) in soluble F1I and intact F1F0I complexes of submitochondrial particles [15].
• Furthermore, studies by cross-linking using dithiobis(succinimidylpropionate) confirmed that the cadherin/catenin complex between Sertoli cells as well as between Sertoli and germ cells indeed structurally linked to actin but not to vimentin (an intermediate filament protein) or to tubulin (a microtubule protein) [16].
• The results further showed that the marrow stromal cells survived the encapsulation in crosslinked gelatin microparticles prepared via exposure to 5mm DSP for 5 min and also retained their proliferative potential and osteoblastic phenotype over a 28 day period, but at a slightly lower level than the EC in uncrosslinked gelatin microparticles [13].
• These binding sites were further characterized by covalent cross-linking of radioiodinated VIP to chicken pineal cell membranes, using dithiobis(succinimidylpropionate) as a cross-linking reagent [17].

Associations of AIDS-129097 with other chemical compounds

• In contrast, aminopeptidase N, used in these studies as a control glycoprotein of the brush border membrane revealed dimeric structures of its single subunit in the presence of dithiobis(succinimidylpropionate) [7].
• Glycerinated, detergent-treated fibers from frog semitendinosus muscle were incubated in 1-10 mM concentrations of dimethylsuberimidate (DMS), dithiobis(succinimidylpropionate) (DTSP) or dimethyl-3,3'-dithiobispropionimidate (DTBP) for 4 h [18].

Gene context of AIDS-129097

• Dithiobis(succinimidylpropionate) (DSP) cross-linking indicated that APP in CG is situated in close proximity with other proteins, possibly with APP itself [19].
• The immunoblot analysis of membranes chemically crosslinked with dithiobis(succinimidylpropionate) showed a broad band at 550-600 kDa suggesting that the GluR4 receptor forms a pentamer in situ [20].
• The present study has made use of a covalent cross-linking reagent, dithiobis(succinimidylpropionate), to study the self-association of prothrombin in the presence of divalent cations [21].
• The 340K protein is most probably a dimeric P-glycoprotein, since only the 180K P-glycoprotein was immunoprecipitated with MRK-16 when K562/ADM cells were treated with the cleavable crosslinking reagent, dithiobis(succinimidylpropionate), and analysed under reduced conditions [22].

Analytical, diagnostic and therapeutic context of AIDS-129097

• In this study, by treating intact cells with a cleavable cross-linker dithiobis(succinimidylpropionate) (DSP), followed by metal chelating chromatography and immunoblotting on secretion-positive strains of X. campestris pv. campestris, we discovered associations of XpsGh with XpsN (GspC), as well as XpsD [23].
• (5) Polypeptide analysis using two-dimensional gel electrophoresis of cross-linked dimers and monomers suggest that subunit VIb is involved in intermonomeric cross-linking of dimeric enzyme by DSP [24].
