Mfn2 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
MFN2 MFN2 (Mitofusin 2) is a mitochondrial outer membrane protein. Essential for mitochondrial fusion and quality control. Linked to CMT2A neuropathy and PD.
Chromosomal location: 1p36.22
MFN2 mutations or dysregulation contribute to neurodegenerative diseases through various mechanisms.
Modulating MFN2 expression or function may have therapeutic potential for neurodegenerative disease treatment.

Mitofusin-2 (MFN2) is a dynamin-like GTPase essential for mitochondrial outer membrane fusion. It plays critical roles in mitochondrial dynamics, quality control, and cellular metabolism[1].
MFN2 mediates mitochondrial outer membrane fusion:
MFN2 is crucial for mitophagy:
MFN2 localizes to mitochondrial-ER contact sites (MERCs):
MFN2 dysfunction in AD:
In PD, MFN2 is implicated through:
MFN2 is the causative gene for CMT2A:
MFN2 links mitochondrial dynamics to metabolism:
MFN2 is ubiquitously expressed with high levels in:
In neurons, MFN2 is localized to somata and synapses, regulating mitochondrial distribution.
Targeting MFN2 function:
