Novel γ-carboxyglutamic acid-containing peptides from the venom of Conus textile
The cone snail is the only invertebrate system in which the vitamin K dependent carboxylase (or γ-carboxylase) and its product γ-carboxyglutamic acid (Gla)1 have been identified. It remains the sole source of ...
Odorant specificity of three oscillations and the DC signal in the turtle olfactory bulb
The odour-induced population response in the in vivo turtle (Terepene sp.) olfactory bulb consists of three oscillatory components (rostral, middle and caudal) that ride on top of a DC signal. In an initial step to determine ...
Kinetochore fiber formation in animal somatic cells : dueling mechanisms come to a draw
The attachment to and movement of a chromosome on the mitotic spindle is mediated by the formation of a bundle of microtubules (MTs) that tethers the kinetochore on the chromosome to a spindle pole. The origin of these ...
The tripartite associations between bacteriophage, Wolbachia, and arthropods
(Public Library of Science (PLoS), 2006-05-19)
By manipulating arthropod reproduction worldwide, the heritable endosymbiont Wolbachia has spread to pandemic levels. Little is known about the microbial basis of cytoplasmic incompatibility (CI) except that bacterial ...

Actin binding to WH2 domains regulates nuclear import of the multifunctional actin regulator JMY
(American Society for Cell Biology, 2012-01-19)
Junction-mediating and regulatory protein (JMY) is a regulator of both transcription and actin filament assembly. In response to DNA damage, JMY accumulates in the nucleus and promotes p53-dependent apoptosis. JMY's ...
Endoplasmic reticulum targeted GFP reveals ER organization in tobacco NT-1 cells during cell division
The endoplasmic reticulum (ER) of plant cells undergoes a drastic reorganization during cell division. In tobacco NT-1 cells that stably express a GFP construct targeted to the ER, we have mapped the reorganization of ...
Arp2/3 complex inhibition radically alters lamellipodial actin architecture, suspended cell shape, and the cell spreading process
(American Society for Cell Biology, 2015-01-07)
Recent studies have investigated the dendritic actin cytoskeleton of the cell edge's lamellipodial (LP) region by experimentally decreasing the activity of the actin filament nucleator and branch former, the Arp2/3 complex. ...
Effects of preservation methods of muscle tissue from upper-trophic level reef fishes on stable isotope values (δ13C and δ15N)
Research that uses stable isotope analysis often involves a delay between sample collection in the field and laboratory processing, therefore requiring preservation to prevent or reduce tissue degradation and associated ...
Augmin-dependent microtubule nucleation at microtubule walls in the spindle
(Rockefeller University Press, 2013-07-01)
The formation of a functional spindle requires microtubule (MT) nucleation from within the spindle, which depends on augmin. How augmin contributes to MT formation and organization is not known because augmin-dependent MTs ...
