  • CD69 transcriptional regulatory elements
    Patent number: 5759805
    Abstract: The present invention provides recombinant polynucleotides comprised of elements that regulate transcription and/or expression of coding sequences. These regulatory elements have been isolated from a CD69 gene, and thus are of particular use in regulating transcription and/or expression in cells which express CD69.
    Type: Grant

    Date of Patent: June 2, 1998
    Assignee: Targeted Genetics Corporation and Immunex
    Inventors: Andrew L. Feldhaus, Steven F. Ziegler
  • Tyrosine kinase
    Patent number: 5447860
    Abstract: A novel receptor protein tyrosine kinase named ork (orphan receptor tyrosine kinase) is identified and characterized. cDNA encoding the ork protein is inserted into an expression vector for production of the protein via recombinant DNA technology. The ork cDNA, when transfected into Cos-7 cells, encodes a 140 Kd protein with in vitro kinase activity. The ork gene is expressed predominantly in placenta and lung, with lower levels in umbilical vein endothelial cells, brain and kidney.
