Traffic COPs: rules of detection.
How specific cargo recognition by coat proteins is achieved and how this recognition event may regulate vesicle formation are still under investigation. In two recent papers by the Owen and Goldberg labs, the binding mode of dilysine motifs to the coatomer of the COPI coat has been analysed. Collectively, their findings suggest that the dilysine motif containing cargo proteins may stabilize coa...
متن کاملMembrane traffic: Cycling lipids
One of the more fascinating problems in biology is to understand the nerve signalling that enables us to think and feel. The transmission of nerve impulses across synapses is accomplished by the release of signalling molecules, known as neurotransmitters, at nerve terminals. Neurotransmitters are stored in synaptic vesicles and, after the nerve has received the appropriate stimulus, they are re...
متن کاملMembrane traffic in anaglyph stereo.
Anaglyphs are stereoscopic image-pairs that are projected through a single optical path and rely on optical filters to separate left and right eye views. In the figures, each image represents digital camera-copy of transmission electron micrographs taken at 910° of specimen tilt, using a standard side-entry goniometer on a transmission electron microscope. Anaglyphs can also be produced today b...
متن کاملAlpine pathways of membrane traffic.
Introduction The Sixth Annaberg Conference continued the success of previous meetings through a combination of interesting talks, lively poster sessions and ample opportunities for the participants to meet informally in the hotel, on the ski slopes and even in the disco. As in previous years, the meeting was held in the medieval Schloss Goldegg near Salzburg, Austria, which provided an unusual ...
متن کاملArf GAPs and membrane traffic.
The selective transfer of material between membrane-delimited organelles is mediated by protein-coated vesicles. In many instances, formation of membrane trafficking intermediates is regulated by the GTP-binding protein Arf. Binding and hydrolysis of GTP by Arf was originally linked to the assembly and disassembly of vesicle coats. Arf GTPase-activating proteins (GAPs), a family of proteins tha...
