Recombinant monoclonal antibodies have entered the clinic as effective in vivo therapeutic. A majority of the therapeutics antibodies employed are intact IgG molecules. IgG-antibody/antigen complexes can activate a wide range of biological responses that result in elimination and destruction of immune complexes. Principle ligands for the activation of clearance (inflammatory) mechanisms are the...
Carbon monoxide releasing molecules (CORMs) have been recently developed for research and pharmacological purposes. A considerable amount of studies demonstrated a wide spectrum of biological activities for lipophilic CORM-2 (tricarbonyldichlororuthenium (II) dimer). It is generally accepted that the liberated gas provides the specific activities to CORMs, with a little attention paid to any po...
Since the aliphatic C-H···anion interaction is relatively weak, anion binding using hydrophobic aliphatic C-H (Cali-H) groups has generally been considered not possible without the presence of additional binding sites that contain stronger interactions to the anion. Herein, we report X-ray structures of organic crystals that feature a chloride anion bound exclusively by hydrophobic Cali-H group...
DNA methylation is an important molecular-level phenotype that links genotypes and complex disease traits. Previous studies have found local correlation between genetic variants and DNA methylation levels (cis-meQTLs). However, general mechanisms underlying cis-meQTLs are unclear. We conducted a cis-meQTL analysis of the Genetics of Lipid Lowering Drugs and Diet Network data (n = 593). We found...
We have investigated the electronic structure of Ru1-xCrxCaO3 using the full potential linearized augmented plane wave method within the local spin density approximation. We have obtained the spin magnetic moment centered at Ru sites from LSDA calculation. The Ru magnetic moment is consistent with the experimental estimates and is lower than the t32g↑t12g↓ electronic configuration. Cr decreas...
Studies of protein-protein interactions play a central role in understanding protein function in biological systems, closing the gap between large-scale sequencing efforts and medically relevant outcomes. Increasingly, protein interaction interfaces that mediate communication between proteins are becoming targets for therapeutics, offering a possibility to disrupt critical interactions and spec...
Staphylococcal nuclease digestion of purified chromatin from duck reticulocytes or calf thymus results in the production of a series of double-stranded DNA fragments of discrete molecular size, ranging from about 130 to 45 base pairs, which can be detected by polyacrylamide gel electrophoresis. Similar patterns of protected DNA fragments are obtained from limit digests of chromatin "reconstitut...
We describe an approach for computational prediction of protein-protein interaction sites using a support vector machine (SVM) classifier. Interface residues and other surface residues were extracted from 115 proteins derived from a set of 70 heterocomplexes in PDB. The SVM classifier was trained to predict whether or not a surface residue is located in the interface based on the identity of th...
Molecular dynamics simulations of the A(2A) adenosine receptor totaling 1.4 μs show clear evidence for specific sites mediating interactions between adenosine-bound A(2A) and cholesterol. The strongest evidence is for three binding sites. Two are in the extracellular leaflet, with one site interacting with helices VII and I, and the other with helices II and III. One site is located in the intr...
