Abstract

Insights

Receptor-interacting protein kinase 3 (RIPK3) regulates necroptosis and impacts mitochondrial function. Understanding RIPK3

Area of Science:

  • Cellular Biology
  • Molecular Biology
  • Hepatology

Background:

  • Receptor-interacting protein kinase 3 (RIPK3) is central to necroptosis, an inflammatory cell death pathway.
  • Necroptosis plays a role in chronic liver diseases like nonalcoholic fatty liver disease and nonalcoholic steatohepatitis.

Purpose of the Study:

  • To review the literature on the role of RIPK3 in mitochondrial bioenergetics.
  • To explore the potential translational applications of targeting RIPK3 in liver disease.

Main Methods:

  • This study is a narrative review based on a PubMed literature search.

Main Results:

  • RIPK3 activation involves post-transcriptional modifications and forms the necrosome complex, potentially including mitochondrial components.
  • RIPK3 influences mitochondrial function by regulating reactive oxygen species, metabolic enzymes, respiratory chain activity, biogenesis, and fatty acid oxidation.

Conclusions:

  • Mitochondrial dysfunction and RIPK3-mediated necroptosis are implicated in chronic liver disease pathogenesis.
  • Further understanding of RIPK3's role in mitochondrial bioenergetics is crucial for potential therapeutic strategies.

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

Translocation of Proteins into the Mitochondria01:19

Translocation of Proteins into the Mitochondria

Mitochondrial precursors are translocated to the internal subcompartments via independent mechanisms involving distinct protein machineries called translocases.
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...

The Inner Mitochondrial Membrane01:28

The Inner Mitochondrial Membrane

The inner mitochondrial membrane is the primary site of ATP synthesis. The inner membrane domain that forms a smooth layer adjacent to the outer membrane is called the inner boundary membrane. This domain contains membrane transporters that drive metabolites in and out of the mitochondria.  In contrast, the inner membrane network that invaginates into the matrix space is called the cristae membrane. This domain accounts for principle mitochondrial function as it accommodates the protein...

Mitochondria01:37

Mitochondria

Mitochondria are eukaryotic cellular organelles that are known to produce energy through a process called oxidative phosphorylation. Besides their primary function, mitochondria are involved in various cellular processes, including cell growth, differentiation, signaling, metabolism, and senescence. Age-related changes cause a decline in mitochondrial quality and integrity due to increased mitochondrial mutations and oxidative damage. Thus, aging can severely impact mitochondrial functions,...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Mitochondrial Membranes01:45

Mitochondrial Membranes

A single mitochondrion is a bean-shaped organelle enclosed by a double-membrane system. The outer membrane of mitochondria is smooth and contains many porins - the integral membrane transporters. Porins enable free diffusion of ions and small uncharged molecules through the outer mitochondrial membrane but limit the transport of molecules larger than 5000 Daltons. Further, the outer mitochondrial membrane forms a unique structure called membrane contact sites with other subcellular organelles,...
