The X-ray crystal structure of the human constitutive androstane receptor (CAR, NR1I3)/retinoid X receptor alpha (RXRalpha, NR2B1) heterodimer sheds light on the mechanism of ligand-independent activation of transcription by nuclear receptors. CAR contains a single-turn Helix X that restricts the conformational freedom of the C-terminal AF2 helix, favoring(More)
Protein chip technology permits analysis of the expression and modification status of numerous targeted proteins within a single experiment, mainly through the use of antibody-based microarrays. Despite recent improvements in these protein chips, their applications are still limited for a variety of reasons, which include technical challenges in fabrication(More)
The sound |faɪv| is visually depicted as a written number word "five" and as an Arabic digit "5." Here, we present four experiments--two quantity same/different experiments and two magnitude comparison experiments--that assess whether auditory number words (|faɪv|), written number words ("five"), and Arabic digits ("5") directly activate one another and/or(More)
The most prominent models of numerical representation posit that numerical symbols are converted into a single internal, abstract representation prior to estimation and comparison processing. Here, we (1) provide a mathematical analysis of the predictions of the abstract-representation hypothesis, assuming the validity of the analog-representation(More)
New technologies are needed that can diagnose cancer more rapidly and accurately. These technologies must also have the ability to identify the particular cellular abnormalities contributing to the malignancy, thus directing the appropriate treatments. Such technologies should permit absolute quantitation of specific tumor biomarkers and their level of(More)
Cdh1 contributes to proper exit from mitosis and maintenance of G(1) phase in eukaryotic cells by activating a large ubiquitin ligase called the anaphase-promoting complex, or cyclosome (APC/C). At the end of G(1), APC/C(Cdh1) is inhibited by cyclin-dependent kinase (CDK) phosphorylation of Cdh1. The specific Cdh1 phosphorylation sites used to regulate(More)
