However, it has been revealed that AIF also participatesin mitochondrial bioenergetics through interaction with its partner coiled-coil-helix-coiled-coil-helix domain containing 4 (CHCHD4) and involvement in mitochondrial protein import. These dual roles place AIF between prosurvival and pro-death cell fate decisions. In this review, we first describe the structure and the dual functions of AIF, highlighting its structure-function relationships. We then report previously identified AIFM1 mutations and their clinical phenotypes. Finally, we discuss the relevance of AIF in cancer and the potential of targeting this protein for the treatment of cancer.  \nKeywords Apoptosis-inducing factor (AIF), Cell death, Mitochondrial protein import, Mitochondrial diseases, Cancer  \nBackground  \nMitochondria - the cellular powerhouse - have been a focus of research for nearly two centuries, yet they remain not fully understood. It has been widely accepted that mitochondria serve as a platform for metabolism and cell fate decisions. This essential organelle facilitates energy production and cellular homeostasis while continuously interacting with other compartments to orchestrate inter-organelle communication [1].

In addition, parts of lipid and pyrimidine metabolisms occur within the mitochondria, and these organelles also regulate the levels of amino acids [2]. In addition to their involvement in metabolism, the mitochondria physically communicate with other intracellular compartments through the outer mitochondrial membrane (OMM), such as the nucleus, endoplasmic reticulum (ER), peroxisomes and lysosomes, thus contributing to numerous processes including signal transduction, calcium homeostasis, vesicle transport, and stress response [2]. This crosstalk with other organelles further highlights the importance of mitochondria in cellular homeostasis by ensuring optimal functions, metabolism, growth and survival.
