Mitochondrial division: New partners in membrane pinching
نویسندگان
چکیده
Mitochondrial division is a complex process requiring the synergistic actions of multiple factors, including mechanical enzymes and accessory proteins. Recent studies have identified a number of these factors and started to elucidate how they act together to bring about mitochondrial fission.

Evidences for a new cation channel in the brain mitochondrial inner membrane
Introduction: Previous studies and our works have indicated several cation channels in the rat brain mitochondrial inner membrane. In this work, we report the single-channel characterization of a cation channel from the rat brain mitochondrial inner membrane incorporated into a planar lipid bilayer. Methods: After removing and homogenizing the adult rat brain, its supernatant was centrifuged...
متن کاملDeveloping of Ethylene Glycol as a New Reducing Agent for Preparation of Pd-Ag/PSS Composite Membrane for Hydrogen Separation
In the present work, for the first time, a palladium-silver membrane has been prepared by electroless plating on the surface of a porous stainless steel disk by using ethylene glycol as a new reducing agent and polyol process. The reducing action of ethylene-glycol in the presence of PVP as a protecting surface agent produces a membrane with finely divided powder and nano-sized pores. Furthermo...
متن کاملInteraction of MDM33 with mitochondrial inner membrane homeostasis pathways in yeast
Membrane homeostasis affects mitochondrial dynamics, morphology, and function. Here we report genetic and proteomic data that reveal multiple interactions of Mdm33, a protein essential for normal mitochondrial structure, with components of phospholipid metabolism and mitochondrial inner membrane homeostasis. We screened for suppressors of MDM33 overexpression-induced growth arrest and isolated ...
متن کاملDivision and DNA synthesis in the kinetoplast ofCrithidia fasciculata.
In Critliidia fascicuJata division of the kinetoplast occurs prior to karyokinesis. Kinetoplast division involves the lateral replication of the nucleoid, and the subsequent constriction and 'pinching off' of the nucleoid and mitochondrial components. Two subunits are produced. DNA synthesis in the kinetoplast and the nucleus is overlapping but asynchronous. Experiments for short labelling time...
متن کاملCharacterization of biophysical properties of single chloride channel in rat brain mitochondrial inner membrane by channel incorporation into bilayer lipid membrane
Introduction: Recent studies have shown the presence of Cl- channels in heart and liver mitochondrial membranes. In this work, we have characterized the functional profile of a Cl- channel from rat brain mitochondria. Methods: After removing and homogenizing the rat brain, the supernatant was separately centrifuged in MSEdigitonin, H2O and Na2CO3 and mitochondrial inner membrane vesicles wer...
