The process of fusion at the nerve terminal is mediated via a specialized set of proteins in the synaptic vesicles and the presynaptic membrane. Three soluble N-ethylmaleimide-sensitive factor (NSF)-attachment protein receptors (SNAREs) have been implicated in membrane fusion. The structure and arrangement of these SNAREs associated with lipid bilayers were(More)
The Na(+)-driven Cl-HCO(3) exchanger (NDCBE or SLC4A8) is a member of the solute carrier 4 (SLC4) family of HCO(3)(-) transporters, which includes products of 10 genes with similar sequences. Most SLC4 members play important roles in regulating intracellular pH (pH(i)). Physiological studies suggest that NDCBE is a major pH(i) regulator in at least(More)
SNAREs (soluble N-ethylmaleimide-sensitive fusion factor attachment protein receptors) are ubiquitous proteins that direct vesicular trafficking and exocytosis. In neurons, SNAREs act to mediate release of neurotransmitters, which is a carefully regulated process. Calcium influx has long been shown to be the key trigger of release. However, calcium alone(More)
Cholinergic synaptic vesicles were isolated from the electric organ of Torpedo californica. Vesicle membrane proteins were reconstituted into planar lipid bilayers by the nystatin/ergosterol fusion technique. After fusion, a variety of ion channels were observed. Here we identify four channels and describe two of them in detail. The two channels share a(More)
Automated isolation of translational efficiency bias that resists the confounding effect of GC(AT)-content Amino acid cost and codon-usage biases in 6 prokaryotic genomes: A whole-genome analysis GA-facilitated knowledge discovery and pattern recognition optimization applied to the biochemistry of protein solvation
The five known Na-coupled HCO(3)(-) transporters (NCBTs) of the solute carrier 4 (SLC4) family play important roles in pH regulation and transepithelial HCO(3)(-) transport. Nearly all of the NCBTs have multiple splice variants. One particular NCBT, the electroneutral Na/HCO(3)(-) cotransporter NBCn2 (SLC4A10), which is predominantly expressed in brain, has(More)
[Purpose] The purposes of this study were: 1) describe a hierarchy of electromyographic activity production, using percentage maximum voluntary contraction of lumbar iliocostalis and lumbar multifidus muscles during prone, quadruped and sitting exercises; and 2) identify optimal recruitment exercises for both lumbar iliocostalis as a global multi-segmental(More)
Cholinergic synaptic vesicles were isolated from Torpedo californica and subjected to repeated freeze/thraw (F/T) cycles. Both vesicular (trapped) and released (free) ATP were measured after each cycle. It was found that a constant percentage of vesicular content was released during each F/T cycle. In solutions low in Ca2+ and Mg2+ and high in sucrose, 25%(More)
