Tetanus toxin is a potent neurotoxin that inhibits the release of neurotransmitters from presynaptic nerve endings. The mature toxin is composed of a heavy and a light chain that are linked via a disulfide bridge. After entry of tetanus toxin into the cytoplasm, the released light chain causes block of neurotransmitter release. Recent evidence suggests that(More)
GTP activates the interaction between the synaptic vesicle proteins rabphilin and rab3. This raises the question of whether rabphilin is a resident vesicle protein that recruits rab3 in a stage-dependent fashion, or if it is instead an effector protein recruited by rab3. We now show that rabphilin, like rab3, dissociates from synaptic vesicles after(More)
Caenorhabditis elegans odr-2 mutants are defective in the ability to chemotax to odorants that are recognized by the two AWC olfactory neurons. Like many other olfactory mutants, they retain responses to high concentrations of AWC-sensed odors; we show here that these residual responses are caused by the ability of other olfactory neurons (the AWA neurons)(More)
