Structural insights into the oligomerization and architecture of eukaryotic membrane pore-forming toxins
(Elsevier, 2011-02)
Pore-forming toxins (PFTs) are proteins that are secreted as soluble molecules and are inserted into membranes to form oligomeric transmembrane pores. In this paper, we report the crystal structure of Fragaceatoxin C (FraC), ...
P2X7R large pore is partially blocked by pore forming proteins antagonists in astrocytes
(Springer Verlag, 2016)
The membranotropic activity of N-terminal peptides from the pore-forming proteins sticholysin I and II is modulated by hydrophobic and electrostatic interactions as well as lipid composition
(Indian Acad Sciences, 2011-12-01)
The sea anemone Stichodactyla helianthus produces two pore-forming proteins, sticholysins I and II (St I and St II). Despite their high identity (93%), these toxins exhibit differences in hemolytic activity that can be ...
Organic additives used as binders and pore-forming elements of TIO2 ceramics
(2017-01-01)
When starches/proteins are added to the ceramic matrix, they originate pores whose morphology and sizes are varied. However, ceramic final properties are influenced by the interaction kinetics amongst particulate materials. ...
Microstructure of ceramics TiO2 obtained by protein consolidation
(2012-11-26)
Porous ceramics can be produced by adding starch (corn, potato) and protein (animal or vegetable) to raw material as pore forming element. In this study, titanium dioxide ceramics were formed by vegetable protein consolidation. ...

Cys mutants in functional regions of Sticholysin I clarify the participation of these residues in pore formation
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Experimental evidence shows that the mechanism of pore formation by actinoporins is a multistep process, involving binding of the water-soluble monomer to the membrane and subsequent oligomerization on the membrane surface, ...
Identification of a membrane-bound prepore species clarifies the lytic mechanism of actinoporins
(American Society for Biochemistry and Molecular Biology, 2016-09)
Pore-forming toxins (PFTs) are cytolytic proteins belonging to the molecular warfare apparatus of living organisms. The assembly of the functional transmembrane pore requires several intermediate steps ranging from a ...
