Functional and Structural Variation among Sticholysins, Pore-Forming Proteins from the Sea Anemone Stichodactyla helianthus. [PDF]

Int J Mol Sci, 2020
Venoms constitute complex mixtures of many different molecules arising from evolution in processes driven by continuous prey–predator interactions. One of the most common compounds in these venomous cocktails are pore-forming proteins, a family of toxins whose activity relies on the disruption of the plasmatic membranes by forming pores.

Stichodactyla helianthus' de novo transcriptome assembly: Discovery of a new actinoporin isoform [PDF]

Toxicon, 2018
Transcriptomic profiling of venom producing tissues from different animals is an effective approach for discovering new toxins useful in biotechnological and pharmaceutical applications, as well in evolutionary comparative studies of venomous animals. Stichodactyla helianthus is a Caribbean sea anemone which produces actinoporins as part of its toxic ...

Panorama of the Intracellular Molecular Concert Orchestrated by Actinoporins, Pore-Forming Toxins from Sea Anemones

Toxins, 2021
Actinoporins (APs) are soluble pore-forming proteins secreted by sea anemones that experience conformational changes originating in pores in the membranes that can lead to cell death. The processes involved in the binding and pore-formation of members of

Determination of the boundary lipids of sticholysins using tryptophan quenching

Scientific Reports, 2022
Sticholysins are α-pore-forming toxins produced by the sea-anemone Stichodactyla helianthus. These toxins exert their activity by forming pores on sphingomyelin-containing membranes.

Identification of scavenger receptors and thrombospondin‐type‐1 repeat proteins potentially relevant for plastid recognition in Sacoglossa

Ecology and Evolution, Volume 10, Issue 21, Page 12348-12363, November 2020., 2020
We investigated the abundance and gene expression of scavenger receptors and thrombospondin‐type‐1 repeat protein superfamily, known to be involved in symbiont recognition, in three plastid‐bearing sea slugs. We could identify candidate receptors, similar to those found in cnidarians for Symbiodinium recognition, that might be relevant in plastid ...

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

Archives of Biochemistry and Biophysics, 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 become integral oligomeric membrane structures that form a pore permeable to cations, which leads to ...

Pharmacological characterization of cnidarian extracts from the Caribbean Sea: evaluation of anti-snake venom and antitumor properties

Journal of Venomous Animals and Toxins including Tropical Diseases, 2018
Background Cnidarians produce toxins, which are composed of different polypeptides that induce pharmacological effects of biotechnological interest, such as antitumor, antiophidic and anti-clotting activities.

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.

Reproductive biology of the sea anemone shrimp Periclimenes rathbunae (Caridea, Palaemonidae, Pontoniinae), from the Caribbean coast of Costa Rica

ZooKeys, 2014
Caridean shrimps are a highly diverse group and many species form symbiotic relationships with different marine invertebrates. Periclimenes rathbunae is a brightly colored shrimp that lives predominantly in association with sea anemones.
