The receptor subtype affinities for these ancestral toxins is currently being elucidated by us. These changes have profound effects on bioactivity, acting upon membrane lipids and proteins of blood cells or heart cells (cardiotoxins) or block the acetylcholine receptor (alpha-neurotoxins like erabutoxin-b).However, just as conservation of structure does not automatically translate to conservation of function, differentiation of structure does not necessarily mean differentiation of function.
