Bestoxin
Bestoxin
Bestoxin (pronounced: /bɛs'tɒksɪn/) is a type of protein that is found in the venom of certain species of spiders. It is known for its ability to block calcium channels, which can lead to various physiological effects.
Etymology
The term "Bestoxin" is derived from the words "best" and "toxin". The "best" part of the name is a reference to the protein's high potency, while "toxin" refers to its toxic nature.
Function
Bestoxin functions by binding to specific sites on voltage-gated calcium channels, thereby blocking the flow of calcium ions into cells. This can disrupt normal cellular functions and lead to various symptoms, such as muscle paralysis.
