چکیده

Currents through sodium channels of neuroblastoma cells were measured using patch technique in outside-out configuration. Scorpion toxin (ScTX) produced 3 to 4 fold prolongation of mean open time and increased number of reopenings. The mean open times showed slow fluctuations around some average values. The distribution of channel open times for ScTX-modified channels required more than one exponential to be fitted. Chloramine-T (ChT) produced qualitatively similar, though weaker, prolongation of open times.

Voltage clamp analysis of sodium channels in normal and scorpion toxin-resistant neuroblastoma cells.

Sodium currents mediated by voltage-sensitive sodium channels in normal and scorpion toxin-resistant neuroblastoma cells were measured using a giga-ohm seal recording method in the whole cell patch configuration. The voltage and time dependence of sodium currents were similar in normal and mutant cell lines. Half-maximal activation occurred for test depolarizations in the range of -7 to -11 mV....

Pumiliotoxin B binds to a site on the voltage-dependent sodium channel that is allosterically coupled to other binding sites.

Pumiliotoxin B (PTX-B), an alkaloid that has cardiotonic and myotonic activity, increases sodium influx in guinea pig cerebral cortical synaptoneurosomes. In the presence of scorpion venom (Leiurus) or purified alpha-scorpion toxin, the PTX-B-induced sodium influx is enhanced severalfold. PTX-B alone has no effect on sodium flux in N18 neuroblastoma cells but, in the presence of alpha-scorpion ...

Voltage-Gated Sodium Channels Modulation by Bothutous Schach Scorpion Venom

Buthotus schach is one of the dangers scorpion in Iran that belong to the Buthidae family. Toxins are existing in venom scorpion, modulate the ion channels by blocking or opening the pore of the channel or by altering the voltage gating and useful as pharmacological tools. In the present study, we investigated the effect of venom and its obtained fractions by gel filtrations on electrophysiolog...

Characterization of cDNA sequence encoding for a novel sodium channel -toxin from the Iranian scorpion Mesobuthus eupeus venom glands

The venoms of Buthidae scorpions are known to contain basic, single-chain protein -toxins consisting of 60-70 amino acid residues that are tightly cross-linked by four disulfide bridges. Total RNA was extracted from the venom glands of scorpion Mesobuthus eupeus collected from the Khuzestan province of Iran and then cDNA was synthesized with the modified oligo (dT) primer and extracted total R...

β-Scorpion Toxin Modifies Gating Transitions in All Four Voltage Sensors of the Sodium Channel

Several naturally occurring polypeptide neurotoxins target specific sites on the voltage-gated sodium channels. Of these, the gating modifier toxins alter the behavior of the sodium channels by stabilizing transient intermediate states in the channel gating pathway. Here we have used an integrated approach that combines electrophysiological and spectroscopic measurements to determine the struct...
