Research Abstract

Biomembranes are various in form, and the diversity of the shapes of biomembranes are critical for cell viability. To understand the function of the shapes in intra-and inter-cellular activities, we attempted to reconstitute in vitro the cristae structure, an invaginated inner membrane of mitochondria, onto liposomes. Using a recombinant protein of LETM1, a mitochondrial protein required for maintenance of the cristae structure, multiple membrane invagination was successfully formed on liposomes.
