Phosphatidylinositol glycan anchor biosynthesis, class C

This gene encodes an endoplasmic reticulum associated protein that is involved in glycosylphosphatidylinositol (GPI) lipid anchor biosynthesis. The GPI lipid anchor is a glycolipid found on many blood cells and serves to anchor proteins to the cell surface. The encoded protein is one subunit of the GPI N-acetylglucosaminyl (GlcNAc) transferase that transfers GlcNAc to phosphatidylinositol (PI) on the cytoplasmic side of the endoplasmic reticulum. Two alternatively spliced transcripts that encode the same protein have been found for this gene. A pseudogene on chromosome 11 has also been characterized. [provided by RefSeq, Jul 2008] (from NCBI)

We also identified 6 missense mutations in DPM2, PIG-C, PIG-N and PIG-P alongside 8 silent mutations.
Saccharomyces cerevisiae Gpi2, an accessory subunit of the enzyme catalyzing the first step of glycosylphosphatidylinositol (GPI) anchor biosynthesis, selectively complements some of the functions of its homolog in Candida albicans.

GPI2 encodes for one of the six accessory subunits of the GPI-N-acetylglucosaminyltransferase (GPI-GnT) complex that catalyzes the first step of GPI biosynthesis in S. cerevisiae and C. albicans.
First step of glycosylphosphatidylinositol (GPI) biosynthesis cross-talks with ergosterol biosynthesis and Ras signaling in Candida albicans.
Komath et al., New Delhi, India. In J Biol Chem, 2014
Using mutational analysis, we show that the accessory subunits, GPI2 and GPI19, of GPI-GnT exhibit opposite effects on ergosterol biosynthesis and Ras signaling (which determines hyphal morphogenesis).
Gpi19, the Saccharomyces cerevisiae homologue of mammalian PIG-P, is a subunit of the initial enzyme for glycosylphosphatidylinositol anchor biosynthesis.

This chemically simple step is genetically complex because three or four genes are required in both yeast (GPI1, GPI2 and GPI3) and mammals (GPI1, PIG A, PIG H and PIG C), respectively.
The human GPI1 gene is required for efficient glycosylphosphatidylinositol biosynthesis.

Six human genes encode subunits of this enzyme, namely PIG-A, PIG-C, PIG-H, PIG-P, GPI1, and DPM2.
Initial enzyme for glycosylphosphatidylinositol biosynthesis requires PIG-P and is regulated by DPM2.

Biosynthesis of GPI is initiated by GPI-N-acetylglucosaminyltransferase (GPI-GnT), which transfers N-acetylglucosamine from UDP- N-acetylglucosamine to phosphatidylinositol. GPI-GnT is a uniquely complex glycosyltransferase, consisting of at least four proteins, PIG-A, PIG-H, PIG-C and GPI1.

Mammalian PIG-A and PIG-C are homologous to yeast GPI3 and GPI2, respectively; however, mammalian PIG-H is not homologous to yeast GPI1.

Homozygous gpi1/gpi1, gpi1::URA3/gpi1::URA3, gpi2/gpi2, and gpi3/gpi3 diploids undergo meiosis, but are defective in ascospore wall maturation for they fail to give the fluorescence due to the dityrosine-containing layer in the ascospore wall.

Under certain conditions endothelial cells have been shown to produce powerful vasodilators, like endothelium-derived relaxing factor (EDRF) and prostacyclin (GPI2), and vasoconstrictors like endothelium-derived constricting factor (EDCF) and endothelin (ET) (Griffith et al., 1988; Vanhoutte & Katusic, 1988).
