Using an acetylcholine-derivatized affinity column, we have purified human alpha4beta2 neuronal nicotinic acetylcholine receptors (nAChRs) from a stably transfected HEK-293 cell line. Both the quantity and the quality of the purified receptor are suitable for applying biochemical methods to directly study the structure of the alpha4beta2 nAChR. In this first study, the lipid-protein interface o...
Nicotinic acetylcholine receptors (nAChR) are cation-selective, ligand-gated ion channels of the cysteine (Cys)-loop gene superfamily. The recent crystal structure of a bacterial homolog from Erwinia chrysanthemi (ELIC) agrees with previous structures of the N-terminal domain of AChBP (acetylcholine-binding protein) and of the electron-microscopy-derived Torpedo nAChR structure. However, the EL...
Surface vessels and submarines must be able to defend themselves against a torpedo attack. Several studies have shown the benefits of multi-platform and multi-static operations. To facilitate torpedo defence system studies and the development of future tactics, TNO Defence, Security and Safety started the development of the Underwater Warfare Testbed (UWT). This testbed integrates the simulatio...
Agrin, an extracellular matrix protein synthesized by nerves and muscles is known to promote the clustering of acetylcholine receptors and other synaptic proteins in cultured myotubes. This observation suggests that agrin may provide at least part of the signal for synaptic specialization in vivo. The extracellular matrix components agrin, laminin and merosin bind to alpha-dystroglycan, a heavi...
Recent evidence suggests that the beta subunit of the Na+ pump is essential for the alpha subunit to express catalytic activity and for assembly of the holoenzyme in the plasma membrane. We report here that injection into Xenopus laevis oocytes of cRNAs specific for beta 1 subunit isoforms of the Na+ pump of four species (Torpedo californica, chicken, mouse and rat) causes a time-dependent incr...
