Inventor(s):	Nathans; Daniel (Baltimore, MD), Linzer; Daniel I. H. (Baltimore, MD)
Assignee:	The Johns Hopkins University (Baltimore, MD)
Application Number:	06/625,499
Patent Claims:	1. A DNA molecule containing a coding sequence free of introns for the amino acid sequence of mammalian proliferin. 2. A DNA molecule containing a coding sequence capable of being transcribed and translated in a procaryote into a protein containing the amino acid sequence of mammalian proliferin. 3. The DNA molecule of claim 1 wherein said molecule is contained within a procaryotic genome. 4. The DNA molecule of claim 3 wherein the coding sequence is associated with a procaryotic regulatory region enabling expression of said amino acid sequence. 5. The DNA molecule of claim 4 contained in a plasmid. 6. The DNA molecule of claim 1 contained in a procaryotic plasmid or bacteriophage vector. 7. The DNA molecule of claim 1 contained in a eucaryotic viral vector. 8. The DNA molecule of claim 7 wherein said viral vector is SV40 virus. 9. The DNA molecule of claim 1 wherein said molecule is contained in a eucaryotic genome. 10. The DNA molecule of claim 9 wherein said eukaryotic genome is contained within a eukaryotic cell and said cell expresses said amino acid sequence. 11. The DNA molecule of claim 10 wherein said amino acid sequence is expressed in a glycosylated form. 12. The DNA molecule of claim 1 containing a coding sequence for the amino acid sequence of proliferin said amino acid sequence being essentially as shown in FIG. 1. 13. The DNA molecule of claim 2 wherein the coding sequence is essentially as shown in FIG. 1. 14. The molecule of claim 1 contained in the plasmid PLF-1 deposited under ATCC Accession No. 39721. 15. A eucaryotic cell transformed by a DNA sequence containing a an intron-free coding sequence for mammalian proliferin and capable of expression as mature mammalian proliferin protein. 16. The cell of claim 15 wherein said DNA sequence is from the same species as said cell. 17. The cell of claim 15 wherein said transformed eucaryotic cell is from a cell line. 18. A cell line produced by clonally expanding the cell of claim 22 into a transformed cell line.
