Mitofusin 2

GC01P011980
GIFtS:
49
This gene encodes a mitochondrial membrane protein that participates in mitochondrial fusion and contributes to the maintenance and operation of the mitochondrial network. This protein is involved in the regulation of vascular smooth muscle cell proliferation, and it may play a role in the pathophysiology of obesity. Mutations in this gene cause Charcot-Marie-Tooth disease type... See more...

Entrez Gene Summary for MFN2 Gene

  • This gene encodes a mitochondrial membrane protein that participates in mitochondrial fusion and contributes to the maintenance and operation of the mitochondrial network. This protein is involved in the regulation of vascular smooth muscle cell proliferation, and it may play a role in the pathophysiology of obesity. Mutations in this gene cause Charcot-Marie-Tooth disease type 2A2, and hereditary motor and sensory neuropathy VI, which are both disorders of the peripheral nervous system. Defects in this gene have also been associated with early-onset stroke. Two transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008]

GeneCards Summary for MFN2 Gene

MFN2 (Mitofusin 2) is a Protein Coding gene. Diseases associated with MFN2 include Charcot-Marie-Tooth Disease, Axonal, Autosomal Dominant, Type 2A2a and Neuropathy, Hereditary Motor And Sensory, Type Via, With Optic Atrophy. Among its related pathways are NOD-like receptor signaling pathway and Mitophagy. Gene Ontology (GO) annotations related to this gene include GTP binding and ubiquitin protein ligase binding. An important paralog of this gene is MFN1.

UniProtKB/Swiss-Prot Summary for MFN2 Gene

  • Mitochondrial outer membrane GTPase that mediates mitochondrial clustering and fusion (PubMed:11181170, PubMed:11950885, 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).

  • Charcot-Marie-Tooth disease 2A2B (CMT2A2B) [MIM:617087]: An axonal form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Neuropathies of the CMT2 group are characterized by signs of axonal degeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. CMT2A2B is a severe form with autosomal recessive inheritance. {ECO:0000269 PubMed:18458227, ECO:0000269 PubMed:20350294, ECO:0000269 PubMed:21715711, ECO:0000269 PubMed:26085578, ECO:0000269 PubMed:26955893}.

  • Charcot-Marie-Tooth disease 2A2A (CMT2A2A) [MIM:609260]: An axonal form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Neuropathies of the CMT2 group are characterized by signs of axonal degeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. {ECO:0000269 PubMed:15064763, ECO:0000269 PubMed:15549395, ECO:0000269 PubMed:16762064, ECO:0000269 PubMed:20350294, ECO:0000269 PubMed:22206013}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Neuropathy, hereditary motor and sensory, 6A (HMSN6A) [MIM:601152]: An autosomal dominant neurologic disorder characterized by optic atrophy and peripheral sensorimotor neuropathy manifesting as axonal Charcot-Marie-Tooth disease. Charcot-Marie-Tooth disease is a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. It is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies and primary peripheral axonal neuropathies. Peripheral axonal neuropathies are characterized by signs of axonal regeneration in the absence of obvious myelin alterations, and normal or slightly reduced nerve conduction velocities. {ECO:0000269 PubMed:16437557, ECO:0000269 PubMed:20350294, ECO:0000269 PubMed:24604904, ECO:0000269 PubMed:26085578}.
