Application

Filipin has been used in a double staining procedure as a probe for the detection of lipoproteins in polyacrylamide gel and immobilized on nitrocellulose membranes. It is also widely used to localize and quantitate unesterified cholesterol by virtue of a specific fluorescent complex.

Biochem/physiol Actions

Filipin is a polyene macrolide antibiotic and antifungal. The antifungal mechanism of action may be due to altering membrane permeability and associated functions by binding to membrane sterols. Filipin inhibits prion protein (PrP) endocytosis and causes the release of PrP from the plasma membrane.

Other Notes

Filipin III is the major component of 8 isomeric components in filipin.

Cholesterol is one of the major lipid components of plasma membrane and it plays an important role in various signaling processes in mammalian cells. Our study focused on the role of membrane cholesterol in organization and dynamics of actin cytoskeleton.

Most cells acquire cholesterol by endocytosis of circulating low-density lipoproteins (LDLs). After cholesteryl ester de-esterification in endosomes, free cholesterol is redistributed to intracellular membranes via unclear mechanisms. Our previous work suggested that the unconventional phospholipid lysobisphosphatidic acid (LBPA) may play

As in other eukaryotes, plant plasma membranes contain sphingolipids, phospholipids, and free sterols. In addition, plant plasma membranes also contain sterol derivatives and usually <5 mol% of a galactolipid, digalactosyldiacylglycerol (DGDG). We earlier reported that compared to fully fertilized oats

Clathrin-mediated endocytosis is essential for a wide range of cellular functions. We used a multi-step siRNA-based screening strategy to identify regulators of the first step in clathrin-mediated endocytosis, formation of clathrin-coated vesicles (CCVs) at the plasma membrane. A primary genome-wide

Brain lipid homeostasis is important for maintenance of brain cell function and synaptic communications, and is intimately linked to age-related cognitive decline. Because of the blood-brain barrier's limiting nature, this tissue relies on a complex system for the synthesis and
