DRP1, fission and apoptosis

Abstract

Abstract Mitochondrial fission is a critical physiological process in eukaryotic cells, participating in various vital activities such as mitosis, mitochondria quality control, and mitophagy. Recent studies have revealed a tight connection between mitochondrial fission and the mitochondrial metabolism, as well as apoptosis, which involves multiple cellular events and interactions between organelles. As a pivotal molecule in the process of mitochondrial fission, the function of DRP1 is regulated at multiple levels, including transcription, post-translational modifications. This review follows the guidelines for Human Gene Nomenclature and will focus on DRP1, discussing its activity regulation, its role in mitochondrial fission, and the relationship between mitochondrial fission and apoptosis.
