Sentence examples for mitochondrial scission from inspiring English sources

We propose that calcineurin, which we speculate might be activated by increased local Ca2+ near compromised mitochondria, will dephosphorylate Drp1 and thus lead to mitochondrial scission as a secondary event.

These sites are also encircled by projections of endoplasmic reticulum that co-localize with Drp1, promote further contraction and lead to eventual mitochondrial scission.

Our selection design would likely have discovered any substantial role for such endocytosis regulators in mitochondrial scission, yet no mutations in genes encoding endocytosis components were identified.

Moreover, association with another organelle system, the endoplasmic reticulum (ER), can determine the location of mitochondrial scission (Friedman et al. 2011).

Much evidence currently supports a model in which cooperative GTP hydrolysis by Dnm1p oligomers at the mitochondrial surface squeezes the mitochondrial tubule, thereby forcing mitochondrial scission (Mears et al. 2011).

Mitochondrial division is mediated by a dynamin-related protein, Dnm1 (in yeast)/Drp1 (in mammals) (Lackner and Nunnari, 2009), which self-assembles in a regulated manner on the surface of the mitochondrial outer membrane into helices that mediate mitochondrial scission (Ingerman et al., 2005; Mears et al., 2011).

Thus, our results and model are fully consistent with previous studies suggesting that tightly regulated actin assembly at ER-mitochondria intersection sites facilitates mitochondrial membrane scission by Drp1 (Friedman et al., 2011; Korobova et al., 2013, 2014; Murley et al., 2013; Hatch et al., 2014; Li et al., 2015).

It is thought that these large scale domain movements drive membrane dynamics such as vesicle scission, mitochondrial and endoplasmic reticulum (ER) fusion, as well as fusion of mitochondrial outer,, and inner membranes., Examples of membrane dynamics in bacteria are less well known since most bacteria lack internal membrane structures or organelles.

The DRP Dnm1/Drp1 (yeast/mammals) drives the scission of mitochondrial membranes, and the DRPs Fzo1/Mfn1/2 and Mgm1/Opa1 mediate fusion of the mitochondrial outer and inner membranes (MOM and MIM), respectively [ 13].

Dnm1/Drp1 assembles into helical structures that wrap around mitochondria and mediate the scission of mitochondrial membranes [ 17, 19- 21].

In contrast to ERMES, our data indicate that Gem1 functions relatively late in ERMD to promote the physical separation of mitochondrial tips generated by membrane scission.
