Molecular Genetics of the Human Red Cell Antigens.
Our laboratory is interested in the molecular genetic bases responsible for the polymorphisms of the human red cell surface antigens; especially interested in the antigens with carbohydrate structure. The research topics that we have implemented during these years include: the ABO blood group glycosyltransferase genes and the rare ABO blood types, Secretor a-1,2-fucosyltransferase gene and the Lewis antigen phenotypes, and the molecular genetics of the I b-1,6-N-acetylglucosaminyltransferase locus and the partial association with congenital cataracts. The expression profiles of the carbohydrate antigens during cell differentiation processes and the regulatory mechanisms of the related glycosyltransferase genes are also our research interests. Currently we endeavor to elucidate the molecular genetic basis for the polymorphism of the P1 (Gala1-4GalNAcb1-3Gal) antigen on red cell surfaces and the expression of I branching carbohydrate structure and the regulatory mechanisms of the I gene transcription during cell differentiation.
