일반 설명
α-Hemolysin, a pore-forming cytotoxin is an extracellular protein secreted by most strains of pathogenic Staphylococcus aureus. It is secreted as a water-soluble monomer and is a small β-barrel protein.
애플리케이션
α-Hemolysin from Staphylococcus aureus has been used:
- as a component of electrolyte solution for testing pore formation in lipid bilayer using electrophysiological measurements
- to test its osteogenesis suppressive effects in bone marrow stromal cells (BMSCs)
- in the preparation of α-hemolysin molecular imprinted polymer (MIP) for Biacore and surface plasmon resonance
α-Hemolysin was used in a study to test the efflux pump and haemolysin activity of Escherichia coli of dairy origin. It was also used to test its adaptation to benzalkonium chloride and the effect of ciprofloxacin on biofilm formation.
생화학적/생리학적 작용
α-Hemolysin is selectively hemolytic and the monomeric form binds to a membrane and specific receptors are not required for binding. Upon binding to biological membranes and/or artificial membranes, self-oligomerization occurs, resulting in ring structures (hexameric aggregates) believed to represent transmembrane pores, which are permeable to ions and small metabolites. It has a marked preference for rabbit red blood cells. α-hemolysin stimulates cellular phospholipases and induces a Ca2+ influx. It leads to membrane disruption of the endothelial barrier and leakage of cytoplasmic components and osmotic lysis of the cells. α-hemolysin is implicated in the pathogenesis of sepsis.

Phosphoinositides (PtdIns) play important roles in exocytosis and are thought to regulate secretory granule docking by co-clustering with the SNARE protein syntaxin to form a docking receptor in the plasma membrane. Here we tested this idea by high-resolution total internal

Staphylococcal alpha-toxin at subcytotoxic concentrations stimulated phosphatidylinositol turnover and arachidonic acid release in undifferentiated cultures of pheochromocytoma PC12 cells. Stimulation of phospholipase A2 but not C was dependent on extracellular calcium. Addition of staphylococcal alpha-toxin to PC12 cells caused a

One key aspect of the virulence of Staphylococcus aureus lies in its ability to target the host cell membrane with a large number of membrane-damaging toxins and peptides. In this review, we describe the hemolysins, the bi-component leukocidins (which include

Signalling by heterotrimeric G proteins is often isoform-specific, meaning certain effectors are regulated exclusively by one family of heterotrimers. For example, in excitable cells inwardly rectifying potassium (GIRK) channels are activated by G betagamma dimers derived specifically from G(i/o) heterotrimers.
