  1. ...These authors contributed equally to this work. Corresponding author: zhipengl@usc.eduAbstractThe recent development and application of methods based on the general principle of “crosslinking and proximity ligation” (crosslink-ligation) are revolutionizing RNA structure studies in living cells. However...
  2. ...(Loughlin et al. 2009). However, such direct repeats were also bound by RBPs having only a single RBD (12 of 27), suggesting that some RBPs could form homodimers or interact to form a homodimer when bound to RNA (Supplemental Table S2). The gap between the direct repeats was generally short, with a median...
  3. ...@fbmc.fcen.uba.arAbstractMost transcription factors, including nuclear receptors, are widely modeled as binding regulatory elements as monomers, homodimers, or heterodimers. Recent findings in live cells show that the glucocorticoid receptor NR3C1 (also known as GR) forms tetramers on enhancers, owing to an allosteric alteration induced...
  4. ...-site-facilitated tethering. We performed ChIP-seq for RNA polymerase II (RNAPII), which is recruited to active enhancers on a global scale (Szutorisz et al. 2005; Koch et al. 2008; Kim et al. 2010), to explore a potential transcriptional function for the prednisolone-regulated sites. A direct correlation was found between...
  5. ...organization in NPs and with previous FRAP analyses of living cells, which demonstrated competition among HMGN variants for chromatin binding sites (Catez et al. 2002). Taken together, the results suggest that loss of an HMGN variant is compensated by increased chromatin binding of the remaining variant...
  6. ...site by iteratively fitting a feature-based generalized linear model to SELEX probe counts. This analysis revealed that the DNA-binding preferences of AR and GR homodimers differ significantly, both within and outside the 15-bp core binding site. The relative preference between the two factors can...
  7. ...it difficult to discern between noise and the true signals. The general concept of binding patterns of global transcription factors is that their target sites are located at promoter regions. Through interacting with RNA polymerase and/or other proteins, and/or hindering the binding of RNA polymerase...
  8. ...et al. 2005 ), and other microfluidic systems ( Thorsen et al. 2002 ; Hong et al. 2004 ). More importantly, recent progress in bioimaging ( Sako et al. 2000 ; Itoh et al. 2002 ; Murakoshi et al. 2004 ; Michalet et al. 2005 ), allowing the study of the dynamic behavior of various proteins in living...
  9. ...structural knowledge, prior knowledge of kinetic parameters, particularly mRNA degradation rate constants, was necessary for the network to be identifiable. Also, with the exception of cases where the noise due to stochastic gene expression was high, complex perturbations were more favorable for identifying...
  10. ...crucial and laborious steps in such fluorescence assay systems is obtaining the protein samples labeled with fluorescent dyes. Most frequently, the proteins have been expressed in living cells, purified to homogeneity, and then fluorescently labeled by chemical modification of the amino, sulfhydryl...
