Identification of Core Alpha 1,3-Fucosyltransferase Gene From Silkworm: An Insect Popularly Used to Express Mammalian Proteins.

ABSTRACT: Silkworm has great potential as production system of recombinant mammalian proteins. When the protein products are used for medical purpose, it is required to reduce the risk of an allergy, the content of core alpha 1,3-fucosyl residue attached to the N-glycan of proteins, for example. We isolated the gene of an enzyme responsible for the transfer of core alpha 1,3-fucosyl residue, core alpha 1,3-fucosyltransferase (Fuc-T C3), from silkworm. A candidate cDNA for silkworm Fuc-T C3 was isolated as a homolog of the fruit fly enzyme gene fucTA. The gene was located on chromosome 7 of the silkworm genome and was composed of seven exons, which spanned approximately 10 kb on the genome. The coding region of the gene was 1,350 bp and encoded a 450-amino acid protein with a molecular mass of 52.2 k
