Controlling Kinesin by Reversible Disulfide Cross-Linking

Conventional kinesin, a dimeric molecular motor, uses ATP-dependent conformational changes to move unidirectionally along a row of tubulin subunits on a microtubule. Two models have been advanced for the major structural change underlying kinesin motility: the first involves an unzippering/zippering of a small peptide (neck linker) from the motor catalytic core and the second proposes an unwind...

Disulfide cross-linking of caldesmon to actin.

Treatment of a solution of actin and smooth muscle caldesmon with 5,5'-dithiobis(2-nitrobenzoic acid) results in the formation of a disulfide cross-link between the C-terminal penultimate residue Cys-374 of actin and Cys-580 in caldesmon's C-terminal actin-binding region. Therefore, these 2 residues are close in the actin-caldesmon complex. Since myosin also binds to actin in the vicinity of Cy...

EBV Latency Types Adopt Alternative Chromatin Conformations

Epstein-Barr Virus (EBV) can establish latent infections with distinct gene expression patterns referred to as latency types. These different latency types are epigenetically stable and correspond to different promoter utilization. Here we explore the three-dimensional conformations of the EBV genome in different latency types. We employed Chromosome Conformation Capture (3C) assay to investiga...

Inhibition of tau aggregation by a rosamine derivative that blocks tau intermolecular disulfide cross-linking.

Abnormal tau aggregates are presumed to be neurotoxic and are an important therapeutic target for multiple neurodegenerative disorders including Alzheimer's disease. Growing evidence has shown that tau intermolecular disulfide cross-linking is critical in generating tau oligomers that serve as a building block for higher-order aggregates. Here we report that a small molecule inhibitor prevents ...

Eukaryotic DNA diverges at a long and complex pyrimidine.purine tract that can adopt altered conformations.

A domain exhibiting major sequence divergences among three cloned repeat units of a complex satellite DNA of the Bermuda land crab contains a repetitive polypyrimidine.polypurine segment consisting of a long C.G tract embedded between runs of CCT.AGG and CGCAC.GTGCG and their variations. The domain adopts at least two types of altered conformations that are markedly affected by pH and negative ...
