Summary: Cell theory has been a cornerstone of biology for over 150 years. Yet how early cells developed into modern forms is still a mystery. The primitive and poorly understood third domain of life, Archaea, should hold clues. Recently, proteins were discovered in archaea that are related to the tubulin proteins of all higher organisms, which provide the structural framework of cells, essential for survival. This project expects to: (1) reveal the basis of how the archaeal tubulin proteins control cell shape in response to environmental change, and (2) develop a new paradigm for archaeal cell biology. The outcomes will provide new insights into the evolution and diversity of cell structure and function.
