Patent
CA 2145657
The present invention provides a novel .beta.1->6 N-acetylglucosaminyltransferase, which forms core 2 oligosaccharide struc- tures in ?-glycans, and a novel acceptor molecule, leukosialin, CD43, for core 2 .beta.1-> 6 N-acetylglucosaminyltransferase activity. The amino acid sequences and nucleic acid sequences encoding these molecules, as well as active fragments thereof, also are dis- closed. A method for isolating nucleic acid sequences encoding proteins having enzymatic activity is disclosed, using CHO cells that support replication of plasmid vectors having a polyoma virus origin of replication. A method to obtain a suitable cell line that expresses an acceptor molecule also is disclosed.
