Abstract
In this review on the transport of glycosylphosphatidylinositol-anchored proteins (GPI-APs), we focus on events that occur in the endoplasmic reticulum after the transfer of GPI to proteins. These events include structural remodeling of both the lipid and glycan moieties of GPI, recruitment of GPI-APs into ER exit sites, association with the cargo receptor, p24 protein complex, and packaging into COPII coated transport vesicles. Similarities with the transport of Wnt proteins are also discussed. This article is part of a Special Issue entitled: Functional and structural diversity of endoplasmic reticulum.
