  • Mammalian cell cycle protein
    Patent number: 6673903
    Abstract: A novel mammalian cell cycle protein, p55CDC, DNA sequences encoding p55CDC, and a method for producing the protein are described. Also described are methods for detecting p55CDC and methods for modulating cell division by compounds which control the level or activity of p55CDC or p55CDC-associated protein complexes.
    Type: Grant
    Filed: April 30, 2001
    Date of Patent: January 6, 2004

  • Method for producing secretable glycosyltransferases and other golgi processing enzymes
    Patent number: 5776772
    Abstract: A method for genetically engineering cells to produce soluble and secretable Golgi processing enzymes instead of naturally occurring membrane-bound enzymes. Cells are genetically engineered to express glycosyltransferases which lack both a membrane anchor and a retention signal. The resulting altered enzyme becomes soluble and secretable by the cell without losing its catalytic activity. Secretion of the soluble glycosyltransferase by the cell provides for increased production and simplified recovery of glycosyltransferase.
    Type: Grant

    Date of Patent: July 7, 1998

  • Process for controlling intracellular glycosylation of proteins
    Patent number: 5047335
    Abstract: A process for controlling the glycosylation of protein in a cell wherein the cell is genetically engineered to produce one or more enzymes which provide internal control of the cell's glycosylation mechanism. A Chinese hamster ovary (CHO) cell line is genetically engineered to produce a sialyltransferase. This supplemental sialyltransferase modifies the CHO glycosylation machinery to produce glycoproteins having carbohydrate structures which more closely resemble naturally occurring human glycoproteins.
