Members of this fungal family of toxins specifically inhibit voltage-gated calcium channels in mammalian cells. They adopt an alpha/beta-sandwich structure, comprising a five-stranded antiparallel beta-sheet with two antiparallel alpha-helices lying at approximately 45 degrees to these strands [1].	Domain
