== Function ==
[https://www.uniprot.org/uniprot/FZO1_YEAST FZO1_YEAST] Essential transmembrane GTPase, which mediates mitochondrial fusion (PubMed:10562274, PubMed:11266460, PubMed:15297626, PubMed:15760898, PubMed:16624808, PubMed:19812251, PubMed:21385840, PubMed:21502136, PubMed:23317502, PubMed:27253069, PubMed:9685359, PubMed:9786948). Fusion proceeds through several steps; first mitochondria are tethered together, then brought into close contact, followed by the formation of a docking ring around contact areas, and finally membrane fusion (PubMed:27253069). Fusion of mitochondria occurs in many cell types and constitutes an important step in mitochondrial morphology, which is balanced between fusion and fission, mediated by FZO1 and DNM1, respectively (PubMed:10562274). Functions antagonistically with DNM1 (PubMed:10562274). Probably acts by forming membrane contact sites that mediate mitochondrial membrane fusion (PubMed:27253069). Mitochondrial docking and fusion requires GTP hydrolysis (PubMed:15297626, PubMed:19812251, PubMed:27253069). Mitochondrial fusion also promotes increased lifespan.<ref>PMID:10562274</ref> <ref>PMID:11266460</ref> <ref>PMID:15297626</ref> <ref>PMID:15760898</ref> <ref>PMID:19812251</ref> <ref>PMID:20505073</ref> <ref>PMID:20550520</ref> <ref>PMID:21385840</ref> <ref>PMID:22353369</ref> <ref>PMID:27253069</ref> <ref>PMID:9685359</ref> <ref>PMID:9786948</ref>
