Research Backgrounds

Function:

Mitochondrial outer membrane GTPase that mediates mitochondrial clustering and fusion. Mitochondria are highly dynamic organelles, and their morphology is determined by the equilibrium between mitochondrial fusion and fission events. Overexpression induces the formation of mitochondrial networks. Membrane clustering requires GTPase activity and may involve a major rearrangement of the coiled coil domains (Probable). Plays a central role in mitochondrial metabolism and may be associated with obesity and/or apoptosis processes (By similarity). Plays an important role in the regulation of vascular smooth muscle cell proliferation (By similarity). Involved in the clearance of damaged mitochondria via selective autophagy (mitophagy). Is required for PRKN recruitment to dysfunctional mitochondria. Involved in the control of unfolded protein response (UPR) upon ER stress including activation of apoptosis and autophagy during ER stress (By similarity). Acts as an upstream regulator of EIF2AK3 and suppresses EIF2AK3 activation under basal conditions (By similarity).

PTMs:

Phosphorylated by PINK1.

Ubiquitinated by non-degradative ubiquitin by PRKN, promoting mitochondrial fusion; deubiquitination by USP30 inhibits mitochondrial fusion.

Subcellular Location:

Mitochondrion outer membrane>Multi-pass membrane protein.
Note: Colocalizes with BAX during apoptosis.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Tissue Specificity:

Ubiquitous; expressed at low level. Highly expressed in heart and kidney.

Subunit Structure:

Forms homomultimers and heteromultimers with MFN1. Oligomerization is essential for mitochondrion fusion (Probable). Interacts with VAT1 (By similarity). Interacts with STOML2; may form heterooligomers. Interacts (phosphorylated) with PRKN. Interacts with EIF2AK3 (By similarity).

Family&Domains:

A helix bundle is formed by helices from the N-terminal and the C-terminal part of the protein. The GTPase domain cannot be expressed by itself, without the helix bundle. Rearrangement of the helix bundle and/or of the coiled coil domains may bring membranes from adjacent mitochondria into close contact, and thereby play a role in mitochondrial fusion.

Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family. Mitofusin subfamily.

Application: WB    Species: Human    Sample:

Figure 7 Mitochondrial dynamics participate in osteogenesis mediated by FGFR/FGFR2-AMPK pathway: (A) Mito-tracker red and mitochondria 2D analysis showed more fragmented or punctate mitochondria with fewer and shorter branches in the MT group, while there were widely reticular mitochondria with longer branches in the WT group. (B) qRT-PCR and Western blot analysis demonstrated that the expressions of mitochondrial-fusion-related factors Mfn2 and Opa1 were downregulated, however, the expression of mitochondrial-fission-related factor Drp1 was upregulated in the MT group compared to the WT group. (C) Mito-tracker red and mitochondria 2D analysis showed a filamentous network of mitochondria with more and longer branches widely spread in the cytoplasm in the siFGFR2 group. (D) qPCR and Western blot analysis showed that the expression of fusion-related genes Mfn2 and Opa1 was increased and the expression of fission-related gene Drp1 was decreased in the siFGFR2 group. (E) After treatment with Compound C, the morphology of the mitochondria which should have tended to split adopted a fused reticular structure with more and longer branches, as shown by Mito-tracker red and mitochondria 2D analysis. (F) Western blot analysis showed the level of MFN2 and OPA1 was increased and then level of DRP1 was decreased, as induced by Compound C. p values were significant at * p < 0.05, ** p < 0.01, *** p < 0.001 and **** p < 0.0001.
