Polarity feeds back
olarizing cells must first pick a direction. The external cues that guide this choice are obvious: bud scars or mating partners for budding yeast, and chemoattractant gradients for Dictyostelium and neutrophils. But polarization still occurs, albeit in a random direction, when these cues are either removed or made uniform. Now, Roland Wedlich-Soldner, Rong Li (Harvard Medical School, Boston, MA...
متن کاملCell Biology: Cytoskeleton Network Topology Feeds Back on Its Regulation
Many cell functions rely on microtubule dynamics and ordering. Two recent studies show that microtubule severing by katanin plays an overbearing role in this process and is primarily regulated at microtubule crossovers.
متن کاملApplied Visual Exploration on Real-time News Feeds using Polarity and Geo-spatial Analysis
This paper presents a visual analytics approach to explore large news article collections in the domains of polarity and spatial analysis. The exploration is performed on the data collected with Europe Media Monitor (EMM), a system which monitors over 2500 online sources and processes 90,000 articles per day. By analyzing the news feeds, we want to find out which topics are important in differe...
متن کاملBub1 autophosphorylation feeds back to regulate kinetochore docking and promote localized substrate phosphorylation
During mitosis, Bub1 kinase phosphorylates histone H2A-T120 to promote centromere sister chromatid cohesion through recruitment of shugoshin (Sgo) proteins. The regulation and dynamics of H2A-T120 phosphorylation are poorly understood. Using quantitative phosphoproteomics we show that Bub1 is autophosphorylated at numerous sites. We confirm mitosis-specific autophosphorylation of a several resi...
متن کاملVRILLE Feeds Back to Control Circadian Transcription of Clock in the Drosophila Circadian Oscillator
The Drosophila circadian oscillator consists of interlocked period (per)/timeless (tim) and Clock (Clk) transcriptional/translational feedback loops. Within these feedback loops, CLK and CYCLE (CYC) activate per and tim transcription at the same time as they repress Clk transcription, thus controlling the opposite cycling phases of these transcripts. CLK-CYC directly bind E box elements to acti...
