Abstract

The discovery of a new protein family in seed plants that is structurally and functionally homologous to animal Mixed lineage kinase domain-like (MLKL) protein, the executioner of necroptosis in animal cells, provided evidence that similar mechanisms may induce plasma membrane permeabilisation in plants and animals. This project aims to understand the molecular principles of MLKL-mediated cell death and immunity by determining and comparing the nanoscale organisation and cellular dynamics of this protein family in plant and animal cells.
