Structural insights into the interaction of smooth muscle myosin with actin have been provided by computer-based fitting of crystal structures into three-dimensional reconstructions obtained by electron cryomicroscopy, and by mapping of structural and dynamic changes in the actomyosin complex. The actomyosin structures determined in the presence and absence(More)
The von Hippel-Lindau (VHL) gene is a well-defined tumor suppressor linked to human heredity cancer syndromes. As a component of the VHL-elongin B/C E3 ligase complex, pVHL performs its tumor function by targeting proteins for proteasomal degradation. It is largely unknown whether pVHL functions in antiviral immunity. In this article, we identify that pVHL(More)
The aim of this study was to examine the role of metabotropic glutamate receptors (mGluR) in the generation of oscillatory field activity at theta frequency (4-12 Hz) in the medial septal slice prepared from rat brain. Bath application of mGluR agonists and antagonists showed that activation of mGluR1-type receptors produces persistent theta frequency(More)
The myosin head (S1) consists of a wide, globular region that contains the actin- and nucleotide-binding sites and an alpha-helical, extended region that is stabilized by the presence of two classes of light chains. The essential light chain abuts the globular domain, whereas the regulatory light chain lies near the head-rod junction of myosin. Removal of(More)
The androgen receptor (AR) plays a pivotal role in prostate homeostasis and prostate cancer development. To understand the mechanism underlying the regulation of the AR holds a promise for developing novel therapeutic approaches for prostate cancer. Here, we show that the Von Hippel-Lindau gene product, pVHL, physically interacts with AR and inhibits AR(More)
Eaf factors play a crucial role in tumor suppression and embryogenesis. To investigate the potential mechanism of Eaf activity, we performed loss- and gain-of-function assays in zebrafish using morpholino and mRNA injections, respectively. We found that eaf1 and eaf2 inhibit Wnt/β-catenin signaling, thereby modulating mesodermal and neural patterning in the(More)
Hypoxia-inducible factor (HIF)-1α and HIF-2α are the main regulators of cellular responses to hypoxia. Post-translational modifications of HIF-1α and 2α are necessary to modulate their functions. The methylation of non-histone proteins by Set7, an SET domain-containing lysine methyltransferase, is a novel regulatory mechanism to control cell protein(More)
Lattice strain plays a crucial role on the properties of nanoparticles. Although the effect of lattice strain on nanoparticles has been widely studied in experimental measurements and calculations, its physical mechanism from the perfective of bond identities is still poorly understood. Herein we put forward an analytical solution of the size effect and(More)
ELL (eleven-nineteen lysine-rich leukemia protein) was first identified as a translocation partner of MLL in acute myeloid leukemia; however, the exact mechanism of its action has remained elusive. In this study, we identified ELL as a direct downstream target gene of E2F1. Coimmunoprecipitation assays showed that ELL interacted with E2F1 in vitro and in(More)
