Fzo_mitofusin

• PFAM accession number: PF04799
• Interpro abstract (IPR006884):

  This entry represents the heptad repeat domain which is conserved at the C terminus of Fzo/mitofusion family of GTPases. Fzo is a mediator of mitochondrial fusion during spermatogenesis [ (PUBMED:9230308) ]. This conserved region is also found in the human mitofusin protein [ (PUBMED:11181170) ].

  This domain forms a dimeric antiparallel coiled coil structure, which has been proposed to act as a mitochodrial tether before vesicle fusion [ (PUBMED:15297672) ].

• GO process: mitochondrial fusion (GO:0008053)
• GO component: integral component of membrane (GO:0016021), mitochondrial outer membrane (GO:0005741)
• GO function: GTPase activity (GO:0003924)

This is a PFAM domain. For full annotation and more information, please see the PFAM entry Fzo_mitofusin
