说明

一般說明

A polypeptide neurotoxin known to pass through the blood-brain barrier. Blocks the AHP-type Ca²⁺-activated K⁺ channel; however, it does not block the TEA and voltage-sensitive Ca²⁺-activated K⁺ channel. Known to induce the secretion of prolactin in a dose-dependent manner.

Polypeptide neurotoxin known to pass through the blood-brain barrier. Blocks the AHP-type Ca²⁺-activated K⁺ channel; does not block the TEA and voltage-sensitive Ca²⁺-activated K⁺ channel. Reported to induce neurodegeneration of Purkinje cells in rat brain. Known to induce the secretion of prolactin in a dose-dependent manner.
