RBBP6 is a 250 kDa splicing-associated protein that has been identified as an E3 ligase due to the presence of a RING finger domain. In humans and mice it interacts with both p53 and Rb, and plays a role in the induction of apoptosis and regulation of the cell cycle. RBBP6 has recently been shown to be highly up-regulated in oesophageal cancer, and to be a(More)
Murine stress-inducible protein 1 (mSTI1) is a co-chaperone that is homologous with the human Hsp70/Hsp90-organizing protein (Hop). Guided by Hop structural data and sequence alignment analyses, we have used site-directed mutagenesis, co-precipitation assays, circular dichroism spectroscopy, steady-state fluorescence, and surface plasmon resonance(More)
The vaccinia virus complement control protein (VCP) is involved in modulating the host inflammatory response by blocking both pathways of complement activity through its ability to bind C3b and C4b. Other activities arise from VCP's ability to strongly bind heparin. To map regions within VCP involved in binding complement and heparin experimentally, surface(More)
The interaction of the Fyn SH3 domain with the p85 subunit of PI3-kinase is investigated using structural detail and thermodynamic data. The solution structure complex of the SH3 domain with a proline-rich peptide mimic of the binding site on the p85 subunit is described. This indicates that the peptide binds as a poly(L-proline) type II helix. Circular(More)
Increasing complexity of design in automotive electrical systems has been paralleled by increased demands for analysis of the safety and reliability aspects of those designs. Such demands can place a great burden on the engineers charged with carrying out the analysis. This paper describes how the intended functions of a circuit design can be combined with(More)
RBBP6 (retinoblastoma binding protein 6) is a 250-kDa multifunctional protein that interacts with both p53 and pRb and has been implicated in mRNA processing. It has also been identified as a putative E3 ubiquitin ligase due to the presence of a RING finger domain, although no substrate has been identified up to now. Using the RING finger domain as bait in(More)
BACKGROUND The Src family of tyrosine kinases is involved in the propagation of intracellular signals from many transmembrane receptors. Each member of the family contains two domains that regulate interactions with other molecules, one of which is the Src homology 3 (SH3) domain. Although structures have previously been determined for SH3 domains, and(More)
Faithful DNA replication is essential for the maintenance of genome integrity. Incomplete genome replication leads to DNA breaks and chromosomal rearrangements, which are causal factors in cancer and other human diseases. Despite their importance, the molecular mechanisms that control human genome stability are incompletely understood. Here, we report a(More)
We present a method that significantly enhances the robustness of (automated) NMR structure determination by allowing the NOE data corresponding to unassigned NMR resonances to be used directly in the calculations. The unassigned resonances are represented by additional atoms or groups of atoms that have no interaction with the regular protein atoms except(More)
