International Journal of Biological Sciences, 2011 A new Cytolysin, termed as Gigantoxin-4, was isolated from the sea anemone Stichodactyla gigantea and found to be highly homologous with Cytolysin-3 (HMg III) from Heteractis magnifica, RTX-A from Radianthus macrodactylus, and Sticholysin-1 (St I) and ...

Kinetics and mechanism of st i modification by peroxyl radicals [PDF]
, 1999 St I is a toxin present in the Caribbean Sea anemone Stichodactyla helianthus which is highly hemolytic in the nanomolar concentration range. Exposure of the toxin to free radicals produced in the pyrolysis of 2,2′ -azobis(2-amidinopropane) hydrochloride

Mechanism of the leakage induced on lipid model membranes by the hemolytic protein sticholysin II from the sea anemone Stichodactyla helianthus [PDF]
European Journal of Biochemistry, 1998 A potent hemolytic polypeptide, sticholysin II, has been purified to homogeneity from the sea anemone Stichodactyla helianthus. The protein produces leakage of aqueous contents of model lipid vesicles composed of either phosphatidylcholine or sphingomyelin if cholesterol is present in these membranes.

Self-homodimerization of an actinoporin by disulfide bridging reveals implications for their structure and pore formation [PDF]
, 2018 The Trp111 to Cys mutant of sticholysin I, an actinoporin from Stichodactyla helianthus sea anemone, forms a homodimer via a disulfide bridge. The purified dimer is 193 times less hemolytic than the monomer.

Insights on the structure-activity relationship of peptides derived from Sticholysin II.
, 2018 Sticholysin II (StII) is a pore-forming actinoporin from the sea anemone Stichodactyla helianthus. A mechanistic model of its action has been proposed: proteins bind to cell membrane, insert their N-termini into the lipid core and assemble into homo ...

Application of stichodactyla toxin in the treatment of autoimmune diseases
, 2018 Stichodactyla helianthus (Ellis, 1768) je vrsta vlasulje prisutna u Karipskom moru. Sadrži neurotoksine koji prvenstveno služe za obranu od predatora. Proučavanje peptida ShK iz ove vrste pokazalo je da osim toksičnog učinka postoji i moguća terapeutska ...

Toxicon, 2008 We have investigated the relationship between the status of red blood cells (RBCs) and their susceptibility to toxin sticholysin II (StII) hemolytic activity; we have evaluated this effect in different RBC ensembles, comprising young and old cells, and in cells partially damaged by their pre-exposition to a free radical source.
