Claims7
An isolated Cytostatin I polypeptide having cell growth inhibition activity comprising a polypeptide having an amino acid sequence which is at least 95% identical to an amino acid sequence selected from the group consisting of:
- (a) amino acid 1 to 107-35 to 212! of SEQ ID NO:2,
- (b) amino acid 39 to 1071 to 212! of SEQ ID NO:2,
- (c) the amino acid sequence of the full-length polypeptide encoded by the cDNA insert contained in ATCC Deposit No. 97103, and
- (d) the amino acid sequence of the mature polypeptide encoded by the cDNA insert contained in ATCC Deposit No. 97103.
An isolated Cytostatin I polypeptide having cell growth inhibition activity comprising a polypeptide having an amino acid sequence at least 95% identical to an amino acid sequence encoded by a polynucleotide sequence selected from the group consisting of:
- (a) the polynucleotide sequence shown in SEQ ID NO:1 as nucleotides 94 to 414, and
- (b) a polynucleotide sequence shown in SEQ ID NO:1 as nucleotides 208 to 414.
An isolated Cytostatin I polypeptide having cell growth inhibition activity comprising a polypeptide having an amino acid sequence which is at least 95% identical to an amino acid sequence encoded by the human cDNA of ATCC Deposit No. 97103.
An isolated Cytostatin-I polypeptide having cell growth inhibition activity comprising a polypeptide having an amino acid sequence, except for at least one conservative substitution, selected from the group consisting of:
- (a) amino acid 1 to 107 of SEQ ID NO:2,
- (b) amino acid 39 to 107 of SEQ ID NO:2,
- (c) the amino acid sequence of the full-length polypeptide encoded by the cDNA insert contained in ATCC Deposit No. 97103, and
- (d) the amino acid sequence of the mature polypeptide encoded by the cDNA insert contained in ATCC Deposit No. 97103.
