Plasticity of the mitochondrial contact site and cristae organizing complex (A10*)

点击翻译按钮获取中文摘要

Mitochondrial morphology varies markedly among different tissues, but the functional ramifications of this structural plasticity remain unclear. Cristae, invaginations of the inner mitochondrial membrane, are among the most flexible structures and the mitochondrial contact site and cristae orga¬nizing (MICOS) complex acts as a key player in controlling their shape. We will study the precise composition and structure of the MICOS complex in different tissues and the functional consequence of its plasticity, to shed light on the mechanisms linking cristae structure to physiological adaptations of mitochondria.
