GDP-L-Fucose Synthase, GDP-4-Keto-6-Deoxy-D-Mannose-3,5-Epimerase-4-Reductase, Protein FX, Red Cell NADP(H)-Binding Protein, Short-Chain Dehydrogenase/Reductase Family 4E Member 1, TSTA3, SDR4E1
GDP-L-Fucose Synthase is a NADP(H)-binding protein. It catalyzes the two-step epimerase and the reductase reactions in GDP-D-mannose metabolism, converting GDP-4-keto-6-D-dexoymannose to GDP-L-fucose. GDP-L-Fucose is the substrate of several fucosyltransferase, involving the expression of mamy glycoconjugates, including blood group ABH antigens and development adhesion antigens. Mutations in the TSTA3 gene may cause leukocyte adhesion deficiency type II.
