Cells sense several kinds of stimuli and trigger corresponding responses through signaling pathways. As a result, cells must process and integrate multiple signals in parallel to maintain specificity and avoid erroneous cross-talk. In this study, we focus our theoretical effort on understanding specificity of a model network system in yeast, Saccharomyces(More)
ETHNOPHARMACOLOGICAL RELEVANCE Baicalin is one of the principal flavonoids isolated from the dried root of Scutellaria baicalensis Georgi that has long been used to treat ischemic stroke. However, its neuroprotective mechanisms against cerebral ischemia injury are poorly understood. AIM OF THE STUDY To explore the neuroprotective mechanisms of baicalin(More)
Effective tiller number is one of the most important traits for wheat (Triticum aestivum L.) yield, but the inheritance of tillering is poorly understood. A set of 168 doubled haploid (DH) lines derivatives of a cross between two winter wheat cultivars (Huapei 3 and Yumai 57), and an immortalized F2 (IF2) population generated by randomly permutated(More)
Pin1 is a peptidyl-prolyl isomerase consisting of a WW domain and a catalytic isomerase (PPIase) domain connected by a flexible linker. Pin1 recognizes phospho-Ser/Thr-Pro motifs in cell-signaling proteins, and is both a cancer and an Alzheimer's disease target. Here, we provide novel insight into the functional motions underlying Pin1 substrate interaction(More)
Four non-magnetic mutants of Magnetospirillum gryphiswaldense strain MSR-1 were isolated by transposon mutagenesis and found to contain interruption of either the mamO or mamE gene within the mamAB operon. Studies indicated that mamO and mamE genes are essential for magnetosome crystal biomineralization in MSR-1. This is the first report of a single gene(More)
To map quantitative trait loci (QTL) and heterotic loci (HL) related to grain number per spike (GNS), 168 double haploid (DH) populations derived from Huapei 3 × Yumai 57 and an immortalized F 2 population (IF 2) generated by randomly permutated intermating of these DH populations were investigated. Using inclusive composite interval mapping (ICIM), a total(More)
Magnetotactic bacteria synthesize magnetic particles called magnetosomes that cause them to orient to their external magnetic fields. However, the physiological significance and other possible functions of these magnetosomes have not been explored in detail. In this study, we have investigated the biological functions of magnetosomes with respect to their(More)
The current canon attributes the binding specificity of protein-recognition motifs to distinctive chemical moieties in their constituent amino acid sequences. However, we show for a WW domain that the sequence crucial for specificity is an intrinsically flexible loop that partially rigidifies upon ligand docking. A single-residue deletion in this loop(More)
Naphthyridine dimer (ND) specially binds to guanine-guanine (G-G) mismatch in duplex DNA. In order to improve the thermal and alkaline stability and binding ability of the ligand, we have examined structural modification of the linker. A new ligand (NNC) possessing 2-amino-1,8-naphthyridines and a carbamate linker is much more thermally stable than ND. The(More)
We report a random delayed-choice quantum eraser experiment. In a Young's double-slit interferometer, the which-slit information is learned from the photon-number fluctuation correlation of thermal light. The reappeared interference indicates that the which-slit information of a photon, or wave packet, can be "erased" by a second photon or wave packet, even(More)
