Malaria parasite CelTOS targets the inner leaflet of cell membranes for pore-dependent disruption

eLife, 2016
Apicomplexan parasites contain a conserved protein CelTOS that, in malaria parasites, is essential for traversal of cells within the mammalian host and arthropod vector.

Structural insights into Clostridium perfringens delta toxin pore formation [PDF]

, 2013
Clostridium perfringens Delta toxin is one of the three hemolysin-like proteins produced by C. perfringens type C and possibly type B strains. One of the others, NetB, has been shown to be the major cause of Avian Nectrotic Enteritis, which following the

Poring over pores: nuclear pore complex insertion into the nuclear envelope

Trends in Biochemical Sciences, 2013
The nuclear boundary is formed by the nuclear envelope (NE), a double membrane system that establishes a selective barrier between the nucleoplasm and the cytoplasm. Its barrier characteristics are determined by nuclear pore complexes (NPCs); huge protein assemblies that guard nucleocytoplasmic compartmentalization.

OmpA: A Pore or Not a Pore? Simulation and Modeling Studies [PDF]

Biophysical Journal, 2002
The bacterial outer membrane protein OmpA is composed of an N-terminal 171-residue beta-barrel domain (OmpA(171)) that spans the bilayer and a periplasmic, C-terminal domain of unknown structure. OmpA has been suggested to primarily serve a structural role, as no continuous pore through the center of the barrel can be discerned in the crystal structure
