Application
Dendrotoxin-K is suitable for use as a potassium voltage-gated channel subfamily A member 1 (Kv1.1) channel blocker in axon and human embryonic kidney (HEK293) cells.[1] It has also been used as a selective blocker of Kv channels in mice.
Biochem/physiol Actions
Dendrotoxin-K (DTXk) is isolated from mamba snake Dendroaspis polylepis and interacts with the β-turn region in the N-terminal sequence of the potassium channel. It inhibits tumor progression in gefitinib-resistant non-small cell lung cancer cells. DTXk induces neuronal damage in the hippocampus via N-methyl-d-aspartate (NMDA) and non-NMDA receptors.
Dendrotoxin-K inhibits potassium channels that contain Kv1.1 protein only.[2]

Dendrotoxin (DTX) homologues are powerful blockers of K+ channels that contain certain subfamily Kv1 (1.1-1.6) alpha- and beta-subunits, in (alpha)4(beta)4 stoichiometry. DTXk inhibits potently Kv1.1-containing channels only, whereas alphaDTX is less discriminating, but exhibits highest affinity for Kv1.2. Herein, the
