Gpi19, the Saccharomyces cerevisiae homologue of mammalian PIG-P, is a subunit of the initial enzyme for glycosylphosphatidylinositol anchor biosynthesis.
Baltimore, United States. In Eukaryot Cell, 2005
The human enzyme has six known subunits, at least four of which, GPI1, PIG-A, PIG-C, and PIG-H, have functional homologs in the budding yeast Saccharomyces cerevisiae.
Endothelium-derived constricting factor(s): the last novelty--endothelin.
Warsaw, Poland. In Clin Physiol, 1990
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).
