Phospholemman/SIMP/Viroporin (PSV) Superfamily

The members of this superfamily are small proteins with a single TMS, although in a few members this TMS is internally duplicated to give 2 TMS proteins. They function as channels and auxiliary transport proteins.

1.A.27 - The Phospholemman (PLM) Family
1.A.95 - The Ephemerovirus Viroporin (EVVP) Family
1.A.100 - The Rhabdoviridae Putative Viroporin, U5 (RV-U5) Family
1.A.113 - The Small Integral Membrane Protein (SIMP) Family
