  • ?1,3-N-acetyl-D-galactosamine transferase protein, nucleic acid encoding the same and method of examining canceration using the same
    Patent number: 8431365
    Abstract: The N-acetyl-D-galactosamine transferase protein of the present invention is characterized by transferring N-acetyl-D-galactosamine to N-acetyl-D-glucosamine with ?1,3 linkage, and it preferably has the amino acid sequence shown in SEQ ID NO: 2 or 4. The canceration assay according to the present invention uses a nucleic acid for measurement which hybridizes under stringent conditions to the nucleotide sequence shown in SEQ ID NO: 1 or 3 or a nucleotide sequence complementary to at least one of them.
    Type: Grant
    Filed: June 29, 2012
    Date of Patent: April 30, 2013
    Assignee: National Institute of Advanced Industrial Science and Technology
    Inventors: Hisashi Narimatsu, Akira Togayachi, Niro Inaba, Toru Hiruma, Yasuko Ishizuka
