Abstract Kalium (http://kaliumdb. org/) is a manually curated database that accumulates data
on potassium channel toxins purified from scorpion venom (KTx). This database is an open …

Tityus kappa (Ts κ), a novel toxin from the venom of the scorpion Tityus serrulatus, is a 35‐
residue polypeptide cross‐linked by three disulphide bridges and acts on small …

K+-channel specific toxins from scorpions are powerful probes used in the structural and
functional characterization of different subfamilies of K+-channels which are thought to be …

Recent studies have demonstrated that scorpion venom contains unique two-domain
peptides with the peculiarity of possessing different functions, ie neurotoxic and cytolytic …

Two new toxins were purified from Leiurus quinquestriatus hebraeus (Lqh) scorpion venom,
Lqh II and Lqh III. Lqh II sequence reveals only two substitutions, as compared to AaH II, the …

Potassium channel functions are often deciphered by using selective and potent scorpion
toxins. Among these toxins, only a limited subset is capable of selectively blocking small …

A full-length cDNA encoding the precursor of a K+ channel toxin (BmTX2) was first isolated
from a venom-gland cDNA library of the Chinese scorpion Buthus martensii Karsch. The …

Voltage-dependent potassium channels belong to a family of structurally related cation
channels that underlie the electrical activity of excitable cells. Many potassium channels are …
