Membrane anchoring of ceil surface proteins by means of glycosyl phosphatidyl-inositol (GPI) anchors is ubiquitous among eucaryotes. GPI anchoring is essential for yeast viability. In mammals, GPI anchoring is not required at the cellular level, but plays an important role in ceil to ceil and ceil to environment interactions which for example are critical during embryogenesis. GPI proteins can...

In eukaryotic cells, a subset of proteins is attached to the outer leaflet of the plasma membrane by a glycosylphosphatidylinositol (GPI) anchor. Apart from providing stable membrane anchorage, GPI anchors are thought to be associated with other functions, such as signal transduction and protein targeting. The biosynthesis of the GPI anchor and its transfer to proteins is highly conserved in...

Proper chromosome segregation is a crucial event for accurate cell division. Defects in chromosome segregation lead to genetic instability and aneuploidy and are correlated with cancer. The laboratory studies chromosome segregation in the budding yeast Saccharomyces cerevisiae. Since this process is highly conserved among eukaryotes, studies in yeast will provide fundamental understanding of this...
