WebSTRUCTURES OF GPI-ANCHORS AND THEIR MICRO-HETEROGENEITY The representative GPI-anchored proteins reported are shown in Table 1. Without exception, GPI anchors are cova-lently linked to carboxyl-terminals of proteins. Figure 2 shows the typical structures of GPI anchors in eucaryotes. The core structure presented for GPI is … WebA mammalian GPI-specific phospholipase D, GPLD1, which is a soluble protein abundant in serum, hydrolyses a set of GPI anchors that have acylated inositol, in contrast to those GPI anchors cleaved by phosphatidylinositol-phospholipase C and GPI-phospholipase C. PGAP6, a GPI-specific phospholipase A 2, has narrow substrate specificity towards ...

Human SND2 mediates ER targeting of GPI-anchored proteins with low hydrophobic GPI attachment signals [J].
WebNational Center for Biotechnology Information WebGPI anchors can undergo remodeling reactions that change the structure of the anchor. An acyl chain attached to the diacylglycerol moiety of inositol is removed and replaced with a longer chain fatty acid. This lipid remodeling event promotes transport of the GPI-modified protein from the ER to the Golgi and is required for interaction of the ...
