General description
Ergosta-5,7,9(11),22-tetraen-3β-ol is an analogue of ergosterol. It comprises of three conjugated double bonds in a steroid ring system. Ergosta-5,7,9(11),22-tetraen-3β-ol possesses anti-inflammatory property. It is used as a cholesterol reporter.
Application
A fluorescent cholesterol analog useful as a probe in membrane research.
Ergosta-5,7,9(11),22-tetraen-3β-ol has been used to examine the acyltransferase activity of lecithin:cholesterol acyltransferase (LCAT). It has also been used for liposome preparation.

Sterol transport between the endoplasmic reticulum (ER) and plasma membrane (PM) occurs by an ATP-dependent, non-vesicular mechanism that is presumed to require sterol transport proteins (STPs). In Saccharomyces cerevisiae, homologs of the mammalian oxysterol-binding protein (Osh1-7) have been proposed to

A new study in this issue (De Saint-Jean et al. 2011. J. Cell Biol. http://dx.doi.org/jcb.201104062) reveals that the sterol transfer protein Osh4p can also transport the signaling phospholipid phosphatidylinositol 4-phosphate (PI(4)P), which binds to the same site in Osh4p as

Uptake of external sterols in the yeast Saccharomyces cerevisiae is a multistep process limited to anaerobiosis or heme deficiency. It includes crossing the cell wall, insertion of sterol molecules into plasma membrane and their internalization and integration into intracellular membranes.
