Inventor(s):	Langley; Keith E. (Newbury Park, CA), DeClerck; Yves A. (Los Angeles, CA), Boone; Thomas C. (Newbury Park, CA)
Assignee:	Amgen Inc. (Thousand Oaks, CA)
Application Number:	07/355,027
Patent Claims:	1. A purified and isolated metalloproteinase inhibitor comprising a polypeptide, wherein said polypeptide; (a) has as a mature protein, an amino terminal amino acid sequence comprising at least the amino acid residues 1 to 42 of FIG. 2, and (b) has at least one biological activity of naturally occurring human metalloproteinase inhibitor, said biological activity selected from the group consisting of in vitro metalloproteinase inhibitor activity and immunological activity. 2. A polypeptide according to claim 1, wherein said polypeptide is the product of procaryotic or eucaryotic expression of an exogenous DNA sequence. 3. A polypeptide according to claim 1 further characterized by being free of association with any mammalian protein. 4. A polypeptide according to claim 2, wherein the exogenous DNA sequence is a cDNA sequence. 5. A polypeptide according to claim 2, wherein the exogenous DNA sequence is carried on an autonomously replicating DNA plasmid or viral vector. 6. A polypeptide according to claim 1, wherein said biological activity of naturally-occurring metalloproteinase inhibitor is immunological activity. 7. A polypeptide according to claim 1, wherein said biological activity of naturally-occurring metalloproteinase inhibitor is in vitro metalloproteinase inhibitor activity. 8. A polypeptide according to claim 1, further characterized by being covalently associated with a detectable label substance. 9. A synthetic polypeptide having part of all of the amino acid sequence as set forth in FIG. 2 and having one or more of the in vitro biological activities of naturally-occurring metalloproteinase inhibitor. 10. A synthetic polypeptide having part or all of the secondary conformation of part or all of the amino acid sequence set forth in FIG. 2 and having a biological property of naturally-occurring human metalloproteinase inhibitor. 11. Purified and isolated human metalloproteinase inhibitor according to claim 1 in glycosylated or nonglycosylated form free of association with any human protein. 12. A pharmaceutical composition comprising an effective amount of a polypeptide according to claim 1 and a pharmaceutically acceptable diluent, adjuvant, or carrier. 13. A polypeptide according to claim 6, wherein said immunological activity is an ability to react with rabbit polyclonal antisera raised against human metalloproteinase inhibitor. 14. A polypeptide according to claim 7, wherein said in vitro biological activity is an ability to inhibit collagenase. 15. A polypeptide according to claim 14, wherein said collagenase is type 1 collagenase.
