A cDNA clone encoding a Xenopus cysteine string protein (Xcsp) was isolated and sequenced. The deduced primary sequence of Xcsp is very similar to other vertebrate csps with the exception of a cysteine residue that lies outside of the cysteine-string

Cysteine string proteins are relatively low mass components of synaptic vesicle membranes. Structurally, their primary sequence is distinguished by a remarkable, cysteine-rich motif. Investigations revealed an unprecedented degree of lipidation of th

1. Ca-selective micro-electrodes were used to measure free Ca concentration in axons and extruded axoplasm. 2. Free Ca in axons immersed in artificial sea water containing 3 mM-Ca averaged 77 nM in freshly dissected axons and 4.9 microM in cyanide- o

Evoked release of transmitter at the squid giant synapse was examined under conditions where the calcium ion concentration in the presynaptic terminal was manipulated by inhibitors of calcium sequestration. Simultaneous intracellular recordings of pr

Barbiturates have had wide use as sedatives, anesthetics and anticonvulsants. Among the sites implicated in the membrane action of barbiturates are the gamma-aminobutyric acidA receptor, receptors for excitatory amino acids and Ca and potassium chann

Kainate receptors are one of the major subtypes of excitatory amino acid receptors in the vertebrate central nervous system. Using Xenopus oocytes injected with RNA from human temporal cortex, it is possible to detect electrophysiologically the expre

Investigations using synaptosomes, pinched-off nerve ending particles from brain, have greatly improved our knowledge of presynaptic function. However, these structures, like most nerve endings, are too small to be penetrated with microelectrodes. We
