Mitofusin-1 is a protein that in humans is encoded by the MFN1 gene. [5] [6] [7] The protein encoded by this gene is a mediator of mitochondrial fusion. This protein and mitofusin 2 are homologs of the Drosophila protein fuzzy onion (Fzo). They are mitochondrial membrane proteins that interact with each other to facilitate mitochondrial ...
Mitochondrial fusion plays an important role in the process of embryonic development, as shown through the Mfn1 and Mfn2 proteins. Using Mfn1 and Mfn2 knock-out mice, which die in utero at midgestation due to a placental deficiency, mitochondrial fusion was shown not to be essential for cell survival in vitro, but necessary for embryonic ...
In mammals MFN1 and MFN2 are essential for mitochondrial fusion. [7] In addition to the mitofusins, OPA1 regulates inner mitochondrial membrane fusion, and DRP1 is responsible for mitochondrial fission. [8] Mitofusin-2 (MFN2) is a mitochondrial membrane protein that plays a central role in regulating mitochondrial fusion and cell
On the other hand, the process of fusion is directed by different membrane-anchored dynamin proteins at different levels of the mitochondria. [13] Fusion at the level of the outer mitochondrial membrane is mediated by Mfn1 and Mfn2 (Mitofusins 1 and 2), [15] and fusion at the level of the inner mitochondrial membrane is mediated by Opa1.
Evidence suggests that mitochondria can also undergo fusion and exchange (in a form of crossover) genetic material among each other. Mitochondria sometimes form large matrices in which fusion, fission, and protein exchanges are constantly occurring. mtDNA shared among mitochondria (despite the fact that they can undergo fusion).

Mitochondrial fission is the process by which mitochondria divide or segregate into two separate mitochondrial organelles. Mitochondrial fission is counteracted by mitochondrial fusion, where two mitochondria fuse together to form a larger one. [1] Fusion can result in elongated mitochondrial networks.
