WebApr 1, 2016 · The GPI-anchored carcinoembryonic antigen became depolarized. Importantly, this lectin was shown to be apically secreted [76]. Galectins belong to the class of secretory proteins that lack signal sequences and get secreted by a mechanism that bypasses the ER and the Golgi complex. Strikingly, when exogenous galectin-9 was … WebGlycosyl phosphatidylinositol-linked blood group antigens and paroxysmal nocturnal hemoglobinuria.

WebAug 1, 1993 · We find that the antigen is a very small glycosylphosphatidylinositol (GPI)-anchored glycoprotein with a mature peptide comprising only 12 amino acids. It can be separated into two distinct antigenic fractions which differ in their susceptibility to phosphatidylinositol-specific phospholipase C. WebCromer antigens are carried on decay accelerating factor (DAF), a complement regulatory protein that is anchored to RBC membrane by GPI and serves to regulate complement activation. DAF is missing from RBCs of patients with paroxysmal nocturnal hemoglobinuria (PNH) because they are deficient in all GPI-linked proteins.
