Caps on
The cost of political campaigns in the U.S. has risen substantially in recent years. For example, real spending on congressional election campaigns doubled between 1976 and 1992 (Steven D. Levitt [1995]). There are many reasons why increased campaign spending might be socially harmful. First, increased spending means increased fund-raising, which may keep politicians from their legislative duti...
متن کاملInvolvement of bristle coat structures in surface membrane formations and membrane interactions during coenocytotomic cleavage in caps of Acetabularia mediterranea
In the multinucleate cap rays of the green alga Acetabularia mediterranea the cell surface increases dramatically within a short time period during the final stages of coenocytotomic cleavage. In early stages of cyst formation the cytoplast is traversed by numerous large and prolate cleavage vesicles which are characterized by typical columellar or spinous coat structures. The cleavage vesicles...
متن کاملCAPS drives trans-SNARE complex formation and membrane fusion through syntaxin interactions.
Ca(2+)-dependent activator protein for secretion (CAPS) is an essential factor for regulated vesicle exocytosis that functions in priming reactions before Ca(2+)-triggered fusion of vesicles with the plasma membrane. However, the precise events that CAPS regulates to promote vesicle fusion are unclear. In the current work, we reconstituted CAPS function in a SNARE-dependent liposome fusion assa...
متن کاملCAPS and syntaxin dock dense core vesicles to the plasma membrane in neurons
Docking to the plasma membrane prepares vesicles for rapid release. Here, we describe a mechanism for dense core vesicle docking in neurons. In Caenorhabditis elegans motor neurons, dense core vesicles dock at the plasma membrane but are excluded from active zones at synapses. We have found that the calcium-activated protein for secretion (CAPS) protein is required for dense core vesicle dockin...
متن کاملCatastrophic antiphospholipid syndrome (CAPS).
Catastrophic antiphospholipid syndrome (CAPS) is a very severe variant of the classic APS, characterised by clinical evidence of multiple organ involvement developing over a very short period of time, histopathological evidence of multiple small vessel occlusions and laboratory confirmation of the presence of antiphospholipid antibodies (aPL), usually in high titre. Although patients with catas...
