structural and functional study of these proteins. This may help improve our understanding of the roles played by individual channel types, as well as assist in the pharmacological classification of these diverse channel types. Furthermore, the availability of radiolabelled dendrotoxins provides a tool for the screening of other sources in a search for new potassium channel toxins, such as the kalicludine class of potassium channel toxins in sea anemones. Lastly, the structural information provided by dendrotoxins may provide clues to the synthesis of
170:(BPTI). Alpha-dendrotoxin and BPTI have been shown to have 35% sequence identity as well as identical disulfide bonds. Despite the structural homology between these two proteins, dendrotoxins do not appear to exhibit any measurable inhibitory protease activity like BPTI. This loss of activity appears to result from the absence of key amino acid residues that produce structural differences that hinder the key interactions necessary for the protease activity seen in BPTI. 5564: 197:(Arg) residues that are concentrated in three primary regions of the protein: near the N-terminus (Arg3, Arg4, Lys5), near the C-terminus (Arg54, Arg55) and at the narrow β-turn region (Lys28, Lys29, Lys30). It is believed that these positively charged residues can play a critical role in dendrotoxin binding activity, as they can make potential interactions with the anionic sites (negatively charged amino acids) in the pore of potassium channels. 111: 244:-helix, play a very important role in the dendrotoxin binding to their potassium channel targets. The lysine residues in the β-turn region has provided more confounding results, appearing to be biologically critical in some dendrotoxin homologues and not necessary for others. Furthermore, mutation of the entire lysine triplet (K28-K29-K30) to Ala-Ala-Gly in alpha-DTX resulted in very little change in biological activity. 248:
interactions of individual toxins to their individual target sites. This not only helps explain the stringent specificity of some dendrotoxins for different subtypes of voltage-gated K channels, but also accounts for differences in the potency of dendrotoxins for common K channels. For example, Wang et al. showed that the interaction of dendrotoxin-K with K

Potassium channels, similar to other cation-selective channels, are believed to have a cloud of negative charges that precede the opening to the channel pore that help conduct potassium ions through the permeation pathway.

1.1 is mediated by its lysine residues in both the N-terminus and the β-turn region, while alpha-dendrotoxin appears to interact with its target solely through the N-terminus. This less expansive interactive domain may help explain why alpha-dendrotoxin is less discriminative while dendrotoxin-K is

There is a general agreement that the conserved lysine residue near the N-terminus (Lys5 in alpha-DTX) is crucial for the biological activity of all dendrotoxins, while additional residues, such as those in the beta-turn region, might play a role in dendrotoxin specificity by mediating the

Many studies have attempted to identify which amino acid residues are important for binding activity of dendrotoxins to their potassium channel targets. Harvey et al. used residue-specific modifications to identify positively charged residues that were crucial to the blocking activity of

and to block the activity of these potassium channels. In this way, dendrotoxins prolong the duration of action potentials and increase acetylcholine release at the neuromuscular junction, which may result in muscle hyperexcitability and convulsive symptoms.
