Research Backgrounds

Function:

Mitochondrial outer membrane GTPase that mediates mitochondrial clustering and fusion. Membrane clustering requires GTPase activity. It may involve a major rearrangement of the coiled coil domains. 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 (in vitro). Has low GTPase activity.

PTMs:

Ubiquitinated by non-degradative ubiquitin by PRKN. Deubiquitination by USP30 inhibits mitochondrial fusion (By similarity). Ubiquitinated by MARCHF5. When mitochondria are depolarized and dysfunctional, it is ubiquitinated by a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex that contains FBXO7 and PRKN.

Subcellular Location:

Mitochondrion outer membrane>Multi-pass membrane protein.

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

Detected in kidney and heart (at protein level). Ubiquitous. Expressed at slightly higher level in kidney and heart. Isoform 2 may be overexpressed in some tumors, such as lung cancers.

Subunit Structure:

Homodimer, also in the absence of bound GTP. Forms higher oligomers in the presence of a transition state GTP analog. Forms homomultimers and heteromultimers with MFN2 (By similarity). Oligomerization is essential for mitochondrion fusion. Component of a high molecular weight multiprotein complex. Interacts with VAT1 (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.
