1.N.9.1.1 | Fusexin1, Fsx1, of 631 aas and 4 TMSs, 1 at the N-terminus and 3 at the C-terminus. It exhibits fusogenic activity and mediates bilateral cell-cell fusion in mammalian cells. Its existence suggests that eukaryotic fusexins arose from prokaryotic fusexins (Moi et al. 2022). | Archaea |
Fsx1 of an uncultured archaeon | |
|
1.N.9.1.2 | Uncharacterized protein of 630 aas and 4 TMSs in a 1 (N-terminus) + 3 (C-terminus) TMS arrangement. | Bacteria |
Chlorobiota | Fuxexin homolog of Chlorobi bacterium |
|
1.N.9.1.3 | HAP2/GCS1 fusexin family protein of 605 aas and 3 TMSs, 1 at the N-terminus and 2 at the C-terminus. | Archaea |
Candidatus Marsarchaeota | Fusexin of Candidatus Marsarchaeota archaeon (mine drainage metagenome) |
