Structural and functional characterization of Sticholysin III: A newly discovered actinoporin within the venom of the sea anemone Stichodactyla helianthus. [PDF]

, 2020
Actinoporins are a family of pore-forming toxins produced by sea anemones as part of their venomous cocktail. These proteins remain soluble and stably folded in aqueous solution, but when interacting with sphingomyelin-containing lipid membranes, they ...

Genomic, functional and structural analyses elucidate evolutionary innovation within the sea anemone 8 toxin family

BMC Biology, 2023
Background The ShK toxin from Stichodactyla helianthus has established the therapeutic potential of sea anemone venom peptides, but many lineage-specific toxin families in Actiniarians remain uncharacterised. One such peptide family, sea anemone 8 (SA8),

Topinambur (Helianthus tuberosus) and yacon (Smallanthus sonchifolius): nutraceutical crops? [PDF]

, 2022
This review is about two crops, topinambur (Helianthus tuberosus L.) and yacón [Smallanthus sonchifolius (Poeppig & Endlicher) H. Robinson], which due to their properties should be considered as nutraceutical foods.

ESTICOLISINA II, UNA CITOLISINA AISLADA DEL ANÉMONA DEL MAR CARIBE Stichodactyla helianthus, INTERACTÚA CON LIPOPROTEÍNAS SÉRICAS, FREUND ANTICUERPOS ADYUVANTES Y ESPECÍFICOS A ESTA PROTEÍNA

Revista de Investigaciones Marinas, 2023
Sticholisina II (St II) es una citolisina aislada de la anémona marina Stichodactyla helianthus. Esta proteína hidrofilica forma poros en las membranas celulares, lo que provoca el desbalance osmótico que conduce a la lisis celular.

Screening and cDNA Cloning of Kv1 Potassium Channel Toxins in Sea Anemones

Marine Drugs, 2010
When 21 species of sea anemones were screened for Kv1 potassium channel toxins by competitive inhibition of the binding of 125I-α-dendrotoxin to rat synaptosomal membranes, 11 species (two species of Actiniidae, one species of Hormathiidae, five species ...

Functional characterization of sticholysin I and W111C mutant reveals the sequence of the actinoporin's pore assembly. [PDF]

PLoS ONE, 2014
The use of pore-forming toxins in the construction of immunotoxins against tumour cells is an alternative for cancer therapy. In this protein family one of the most potent toxins are the actinoporins, cytolysins from sea anemones.
