Mitochondrial Fission and Fusion: Molecular Mechanisms, Biological Functions, and Related Disorders
Membranes, 2022 Mitochondria are dynamic organelles that undergo fusion and fission. These active processes occur continuously and simultaneously and are mediated by nuclear-DNA-encoded proteins that act on mitochondrial membranes. The balance between fusion and fission

Hsp70 in mitochondrial biogenesis [PDF]
, 1994 The family of hsp70 (70 kilodalton heat shock protein) molecular chaperones plays an essential and diverse role in cellular physiology, Hsp70 proteins appear to elicit their effects by interacting with polypeptides that present domains which exhibit non ...

Anomalous diffusion induced by cristae geometry in the inner mitochondrial membrane [PDF]
, 2009 Diffusion of inner membrane proteins is a prerequisite for correct functionality of mitochondria. The complicated structure of tubular, vesicular or flat cristae and their small connections to the inner boundary membrane impose constraints on the ...

A dimeric equilibrium intermediate nucleates Drp1 reassembly on mitochondrial membranes for fission
Molecular Biology of the Cell, 2014 Drp1 catalyzes mitochondrial division, but the mechanisms remain elusive. The mitochondrial lipid cardiolipin stimulates Drp1 activity and supports membrane constriction.

Mitochondrial Membrane Potential Assay [PDF]
, 2016 Mitochondrial function, a key indicator of cell health, can be assessed by monitoring changes in mitochondrial membrane potential (MMP). Cationic fluorescent dyes are commonly used tools to assess MMP. We used a water-soluble mitochondrial membrane potential indicator (m-MPI) to detect changes in MMP in HepG2 cells.

MOM19, an import receptor for mitochondrial precursor proteins [PDF]
, 1989 We have identified a 19 kd protein of the mitochondrial outer membrane (MOM19). Monospecific IgG and Fab fragments directed against MOM19 inhibit import of precursor proteins destined for the various mitochondrial subcompartments, including porin ...

A mitochondrial import receptor for the ADP/ATP carrier [PDF]
, 1990 We have identified a mitochondrial outer membrane protein of 72 kd (MOM72) that exhibits the properties of an import receptor for the ADP/ATP carrier (AAC), the most abundant mitochondrial protein.

Successive translocation into and out of the mitochondrial matrix [PDF]
, 1987 We investigated the import and sorting pathways of cytochrome b2 and cytochrome c1, which are functionally located in the intermembrane space of mitochondria.
