Abstract Dynamin related protein 1 (DRP1), a pivotal mitochondrial fission protein, is post-translationally modified by multiple mechanisms. Here we identify new post-translational modification of DRP1 the ubiquitin-like interferon-stimulated gene 15 (ISG15). ISGylation mediated ISG15 E3 ligase, HERC5; this promotes fission. DeISGylation however leads to hyperfusion. Heterologous expression SARS-CoV2 PLpro, deISGylating enzyme, results in similar filamentation, significant decrease total levels and efflux mtDNA. We report that deISGylated gets ubiquitylated degraded TRIM25, instead PARKIN MITOL. While cytosolic pool primarily ISGylated, both fractions may be ubiquitylated. It known phosphorylation at S616 residue regulates its localisation; show phospho-DRP1 (S616) renders competence mitochondria. This because affects functionality dynamics Alzheimer’s disease pathophysiology.

Mitochondria are well known as organelles responsible for the maintenance of cellular bioenergetics through production ATP. Although oxidative phosphorylation may be their most important function, mitochondria also integral synthesis metabolic precursors, calcium regulation, reactive oxygen species, immune signaling, and apoptosis. Considering breadth responsibilities, fundamental metabolism homeostasis. Appreciating this significance, translational medicine has begun to investigate how mitochondrial dysfunction can represent a harbinger disease. In review, we provide detailed overview metabolism, bioenergetics, dynamics, autophagy, damage-associated molecular patterns, mitochondria-mediated cell death pathways, at any these levels is associated with disease pathogenesis.
