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 22°C. 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.

Supplementary information

Mitofusin 2 also known as MFN2 is a protein involved in the regulation of mitochondrial fusion. The MFN2 molecular weight is roughly 86 kDa. It plays an important role in connecting and merging the outer membranes of mitochondria which is vital for maintaining mitochondrial function and integrity. Mitofusin 2 proteins are expressed in many tissues but they are abundantly present in energy-demanding tissues like skeletal muscle heart and the brain.
Biological function summary

Mitofusin 2 ensures the proper distribution of mitochondria within cells and regulates mitochondrial metabolism. It is a critical component of the mitochondrial fusion machinery and works closely with its homolog Mitofusin 1 (MFN1). Together they form a complex that facilitates the physical merging of mitochondrial membranes. This process is essential for mitochondrial dynamics which include not only fusion but also fission and biogenesis.

Pathways

The protein part of the fusion machinery integrates into multiple essential biological pathways including energy metabolism and apoptosis regulation. It participates in the mitochondrial fusion pathway and the PGC-1α pathway for mitochondrial biogenesis. Mitofusin 2 interacts with proteins such as PINK1 and Parkin that are known to play roles in mitophagy a process that targets damaged mitochondria for degradation indicating its involvement in maintaining mitochondrial quality control.

Mutations in Mitofusin 2 have been linked to Charcot-Marie-Tooth disease type 2A (CMT2A) a neuropathy that affects peripheral nerves. This protein also shows connections to metabolic disorders such as obesity and type 2 diabetes. In these conditions its interaction with other proteins like OPA1 involved in mitochondrial inner membrane fusion influences mitochondrial dysfunction a recognized feature contributing to disease pathogenesis. Understanding MFN2's function and role in disease can help develop targeted therapies for these conditions.

Target data

Mitochondrial outer membrane GTPase that mediates mitochondrial clustering and fusion (PubMed : 11181170, PubMed : 11950885, PubMed : 19889647, PubMed : 26214738, PubMed : 28114303). Mitochondria are highly dynamic organelles, and their morphology is determined by the equilibrium between mitochondrial fusion and fission events (PubMed : 28114303). Overexpression induces the formation of mitochondrial networks (PubMed : 28114303). 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) (PubMed : 23620051). Is required for PRKN recruitment to dysfunctional mitochondria (PubMed : 23620051). 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).
