The structure and occurrence of cubic membranes

While the structure of these cubic membranes does represent, to date, an enigma, their functional role is an even more challenging issue since virtually nothing is known of it. Undoubtedly, structure-function relationships, so successfully applied to many other areas of science, could prove to be equally fruitful when applied to cubic membranes, as briefly addressed below. In the following sections we will highlight some of our structural findings. The outline will largely follow the order of appearance in Tables 7.1 and 7.2.
