mitofusin

mitofusin

(mī-tō-fyū'zhun),
Process in which mitochondria of healthy cells undergo fusion; the course of action occurs in three steps, first, the mitochondria align themselves, end to end; next, the outer membranes of the two organelles fuse with each other; and last, the inner membranes fuse with each other, thus forming a larger mitochondrion.

Additionally, the dynamin-related GTPase mitofusin 2 (Mfn2) proteins located on the ER intermingle with Mfn1 or Mfn2 on mitochondria to tighten the connection.
Moreover, observed upregulation of mir-140, which exerts effect on mitochondrial fission and apoptosis through targeting mitofusin 1 (Mfn1), may be directly correlated with frequently observed in [ASC.sub.EMS] mitochondrial fission.

Mitofusin 1/2 (Mfn1/2) and optic atrophy1 (Opa1) are known to induce mitochondrial fusion [44, 45], while dynamin-related protein 1 (Drp1) is identified to interact with fission protein 1 (Fis1) to promote mitochondrial fission [46, 47].

In animal models, mitofusin 2 (Mfn2) plays a key role in mitochondrial muscle damage control, since in the aging process there is a progressive Mfn2 reduction in the skeletal muscle of the mice, besides, the Mfn2 ablation produces a gene mark of aging.

Fission and fusion mitochondrial dynamics are controlled by groups of dynamins: GTPases [60, 73] among them standout DRP-1 (dynamin-related protein 1), Mfn (Mitofusin), and OPA (optic atrophy protein-1) [74].
