ABSTRACT:
The present invention provides a novel polypeptide having a β1,3-N-acetylglucosaminyltransferase activity; a method for producing the polypeptide; a DNA which encodes the polypeptide; a recombinant vector into which the DNA is inserted; a transformant comprising the recombinant vector; a method for producing a sugar chain or complex carbohydrate, using the polypeptide; a method for producing a sugar chain or complex carbohydrate, using the transformant; an antibody which recognizes the polypeptide; a method for screening a substance which changes the expression of the gene which encodes the polypeptide; and a method for screening a substance which changes the activity of the polypeptide.
