  • Function

    Essential transmembrane GTPase, which mediates mitochondrial fusion. Fusion of mitochondria occurs in many cell types and constitutes an important step in mitochondria morphology, which is balanced between fusion and fission. MFN2 acts independently of the cytoskeleton. It therefore plays a central role in mitochondrial metabolism and may be associated with obesity and/or apoptosis processes. Overexpression induces the formation of mitochondrial networks. Plays an important role in the regulation of vascular smooth muscle cell proliferation. Involved in the clearance of damaged mitochondria via selective autophagy (mitophagy). Is required for PARK2 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. Acts as an upstream regulator of EIF2AK3 and suppresses EIF2AK3 activation under basal conditions.
  • Tissue specificity

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

    Charcot-Marie-Tooth disease 2A2
    Neuropathy, hereditary motor and sensory, 6A
  • Sequence similarities

    Belongs to the TRAFAC class dynamin-like GTPase superfamily. Dynamin/Fzo/YdjA family. Mitofusin subfamily.
    Contains 1 dynamin-type G (guanine nucleotide-binding) domain.
  • Post-translational

    Phosphorylated by PINK1.
    Ubiquitinated by non-degradative ubiquitin by PARK2, promoting mitochondrial fusion; deubiquitination by USP30 inhibits mitochondrial fusion.
  • Cellular localization

    Mitochondrion outer membrane. Colocalizes with BAX during apoptosis.
