iberiotoxin from buthus tamulus

Description:

Iberiotoxin, derived from the venom of the Indian red scorpion (Buthus tamulus), is a potent neurotoxin known for its selective inhibition of certain potassium channels, particularly the voltage-gated potassium channels (Kv) in excitable tissues. This characteristic makes it a valuable tool in neuropharmacology for studying ion channel function and the physiological roles of potassium channels in various cellular processes. Iberiotoxin exhibits a high affinity for the Kv1.3 channel, which is implicated in immune responses and neuronal excitability. The toxin's structure is characterized by a polypeptide chain that folds into a specific three-dimensional conformation, allowing it to interact effectively with its target channels. Its mechanism of action involves binding to the channel and preventing potassium ion flow, which can lead to prolonged depolarization of neurons and muscle cells. Due to its potent effects, iberiotoxin is also of interest in research related to pain, inflammation, and potential therapeutic applications, although its use is primarily confined to laboratory settings due to its toxicity.

Iberiotoxin

CAS: 129203-60-7

Iberiotoxin (IbTx), from the venom of the scorpion Buthus tamulus, shows 68% sequence homology with charybdotoxin, another scorpion-derived peptidyl toxin. Although these two toxins both inhibit the high conductance Ca²⁺ activated K⁺ channel, they appear to bind at different sites on the channel and modulate channel activity by different mechanisms. Thus, iberiotoxin can be used to selectively study the function of the high conductance Ca²⁺ activated K⁺ channel.

Iberiotoxin

CAS: 129203-60-7

Iberiotoxin is a neurotoxin that is synthesized by the bacterium Clostridium botulinum. It inhibits the activity of a number of enzymes, including protein kinase C and cyclase, but has no effect on phosphatases. Iberiotoxin has been shown to be effective against models systems of bowel disease, such as colonic inflammation and ulceration. Iberiotoxin binds to specific neuronal receptors in the central nervous system, leading to inhibition of intracellular calcium levels, which may play an important role in the mechanisms of action for this toxin.
