Acta Chimica Slovenica
|September 25, 2013
Summary
Cnidarian toxins, particularly cytolysins, form pores in cell membranes. This study details the physiological roles of membrane permeabilization and characterizes these protein toxins.
Area of Science:
- Marine Biology
- Biochemistry
- Toxicology
Background:
- Cnidarians produce diverse toxins for defense and signaling.
- Cytolytic toxins are a key component of cnidarian weaponry.
- Pore formation in cell membranes is a significant mechanism of toxicity.
Purpose of the Study:
- To elucidate the physiological relevance of membrane permeabilization by cnidarian toxins.
- To present data on proteinaceous cnidarian cytolysins.
- To characterize cytolysins that damage cell membranes via pore formation.
Main Methods:
- Literature review and data compilation on cnidarian cytolysins.
- Analysis of functional and structural characteristics of selected cytolysins.
- Physiological relevance assessment of membrane permeabilization.
Main Results:
- Cnidarian cytolysins are proteinaceous toxins.
- These toxins permeabilize cell membranes through pore formation.
- Partial functional and structural characterization of several cytolysins is presented.
Conclusions:
- Cnidarian cytolysins represent a significant class of membrane-disrupting toxins.
- Understanding their mechanisms is crucial for toxicology and potential applications.
- Further characterization of these toxins is warranted.

01:27Diversity of Protists II
Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
01:23Catenins
Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the adherens...

01:02Role of Septins
Septins are the recently discovered fourth major protein component of the cytoskeleton, along with microfilaments, microtubules, and intermediate filaments. These proteins can associate with other cytoskeletal filaments and carry out varied roles or can be free-floating in the cytoplasm.
Cellular Functions of Septins
Recent studies have revealed the multifaceted roles of septins in various cellular processes such as cytokinesis, ciliogenesis, and neurogenesis. Septins act as scaffolds and...

01:29Cytoskeletal Proteins in Bacteria
Bacterial cells were initially considered simple, randomly organized structures lacking a cytoskeleton. However, the discovery of cytoskeleton homologs in bacteria led to the change of this opinion. Bacterial cytoskeletal filaments regulate the cell shape, cell polarity, cell division, and partitioning of plasmids during cell division. It was later discovered that bacterial cytoskeletal proteins, mainly actin and tubulin homologs, are diverse compared to their eukaryotic counterparts. On the...
01:05Mechanism of Ciliary Motion
The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...

01:24Cytoplasm
The cytoplasm consists of organelles and a framework of protein scaffolds called the cytoskeleton suspended in an aqueous solution, the cytosol. The cytosol is a rich broth of water, ions, salts, and various organic molecules.
Protein Folding and Misfolding
The cytoplasm is the location for several cellular processes, including protein synthesis and folding. The aqueous nature of the cytosol promotes protein folding such that the hydrophobic amino acid side chains are buried in the protein...
