Huwentoxin-I

Huwentoxin-I – Ion Channels and Transporters Huwentoxin-I (HwTx-I) is a neurotoxin that was originally isolated from the venom of the Chinese bird spider Ornithoctonus huwena. Huwentoxin-I is known to be an inhibitor of tetrodotoxin-sensitive voltage-gated...

HsTx1

HsTx1 – Ion Channels and Transporters HsTx-1 is a member of the a-KTx6 family of scorpion toxins active on voltage-gated Kv1.3 channels (Kd close to 10 pM). HsTx-1 is also very active on Kv1.1 channels (IC50 around 7 nM). It is however inactive on...

Hm1a

Hm1a – Ion Channels and Transporters Hm1a has been identified from the venom of the spider Heteroscodra maculata. Hm1a has been described as a potent and selective agonist of the voltage-gated sodium channel Nav1.1 with an EC value of 38 nM. Nav1.1 is expressed...
