<unk> s have close homology to other inhibitor cystine knot (ICK) toxins. ICK toxins are best known as blockers of cation channels. The exact structure of the VaTxs has not yet been deduced, although some preliminary models have been proposed. VaTxs are 53-82% identical in amino acid sequence. VaTx1 and VaTx2 have an almost identical structure, while VaTx3 shows some diversity in its extruding protein loop.
