An isolated polypeptide comprising the amino acid sequence of a polypeptide selected from the group consisting of:
- (a) a polypeptide comprising an amino acid sequence having at least 95% amino acid identity with SEQ ID NO:2 and with amino acids 82-101 of SEQ ID NO:2, wherein said polypeptide comprises amino acids 376-395 of SEQ ID NQ:2 and has protease inhibitory activity;
- (b) a polypeptide of (a) that comprises an amino acid sequence selected from the group consisting of amino acids 61-107 of SEQ ID NO:2 and amino acids 82-101 of SEQ ID NO:2;
- (c) a polypeptide of (a) that comprises amino acids 398-408 of SEQ ID NQ:2;
- and
- (d) a polypeptide according to any of (a) through (c), wherein said polypeptide binds specifically with an antibody that also binds specifically with a Thypin polypeptide having an amino acid sequence as shown in SEQ ID NQ:2.
An isolated polypeptide encoded by a nucleic acid molecule that is capable of hybridizing under highly stringent conditions with the complement of the nucleotide sequence of SEQ ID NO:1, wherein said highly stringent conditions comprise hybridizing at 42° C. in 50% formamide and 6×SSC and washing at 68° C. in 0.2×SSC, said polypeptide having protease inhibitory activity and comprising an amino acid sequence having at least 95% amino acid identity with SEQ ID NQ:2 and comprising amino acids 376-395 of SEQ ID NO:2, and further wherein said polypeptide comprises an amino acid sequence selected from the group consisting of amino acids from 61 to 107 of SEQ ID NQ:2 and amino acids from 82 to 101 of SEQ ID NO:2, and also comprises amino acids from 398 to 408 of SEQ ID NQ:2.
