Target

  • 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
    modifications
    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.

    Predicted band size : 86 kDa
  • ab56889 staining mitofusin 2 in MEF1 cells treated with nigericin Na+ salt (ab120494), by ICC/IF. Decrease in mitofusin 2 expression correlates with increased concentration of nigericin Na+ salt, as described in literature.
    The cells were incubated at 37°C for 3h in media containing different concentrations of ab120494 (nigericin Na+ salt) in DMSO, fixed with 100% methanol for 5 minutes at -20°C and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab56889 (10 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight® 488 goat anti-mouse polyclonal antibody (ab96879) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

  • Mitofusin 2 antibody (ab56889) used in immunohistochemistry at 3ug/ml on formalin fixed and paraffin embedded human kidney.

  • Overlay histogram showing HEK293 cells stained with ab56889 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab56889, 1µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HEK293 cells fixed with 4% paraformaldehyde (10 min)/permeabilized in 0.1% PBS-Tween used under the same conditions.

  • ab56889 staining mitofusin2 in MEF1 cells treated with valinomycin from Streptomyces fulvissimus (ab120852), by ICC/IF. Decrease in mitofusin2 expression with increased concentration of withaferin valinomycin from Streptomyces fulvissimus, as described in literature.
    The cells were incubated at 37°C for 3h in media containing different concentrations of ab120852 (valinomycin from Streptomyces fulvissimus) in DMSO, fixed with 100% methanol for 5 minutes at -20°C and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature.
