Determination of variant pathogenicity represents a major challenge in the era of high-throughput sequencing. Erroneous categorization may result if variants affect genes that are in fact dispensable. We demonstrate that this also applies to rare, apparently unambiguous truncating mutations of an established disease gene. By whole-exome sequencing (WES) in(More)
WD40-repeat proteins (WD40s), as one of the largest protein families in eukaryotes, play vital roles in assembling protein-protein/DNA/RNA complexes. WD40s fold into similar β-propeller structures despite diversified sequences. A program WDSP (WD40 repeat protein Structure Predictor) has been developed to accurately identify WD40 repeats and predict their(More)
The enantioselective Pd-catalyzed redox-relay Heck arylation of acyclic alkenyl alcohols allows access to various useful chiral building blocks from simple olefinic substrates. Mechanistically, after the initial migratory insertion, a succession of β-hydride elimination and migratory insertion steps yields a saturated carbonyl product instead of the more(More)
The analysis of 36 available crystal structures of WD40 repeat proteins reveals widespread existence of a beta-bulge formed at the beginning of strand a and the end of strand b, termed as WD(b-a) bulge: among a total of 259 WD40 blades, there are 243 such β-bulges. The R(1) positions in these WD(b-a) bulges have fair distributions of Arg, His, Ile, Leu,(More)
We describe a consanguineous Iraqi family with Leber congenital amaurosis (LCA), Joubert syndrome (JBTS), and polycystic kidney disease (PKD). Targeted next-generation sequencing for excluding mutations in known LCA and JBTS genes, homozygosity mapping, and whole-exome sequencing identified a homozygous missense variant, c.317G>C (p.Arg106Pro), in POC1B, a(More)
WD40-repeat proteins, as one of the largest protein families, often serve as platforms to assemble functional complexes through the hotspot residues on their domain surfaces, and thus play vital roles in many biological processes. Consequently, it is highly required for researchers who study WD40 proteins and protein-protein interactions to obtain(More)
The interaction between the HIV gp120 protein and coreceptor CCR5 or CXCR4 of the host cell is critical in mediating the HIV entry process. A model for the CCR5-gp120 complex has been developed. In the model, the N-terminus of CCR5 binds to three discontinuous domains of gp120, including the fourth conserved (C4) region, β19/β20 connecting loop, and V3(More)
Histone deacetylases (HDACs) have found intense interest as drug targets for a variety of diseases, but there is disagreement about basic aspects of the inhibition and mechanism of HDACs. QM/MM calculations of HDAC8 including a large QM region provide a model that is consistent with the available crystal structures and structure-activity relationships of(More)
