Ti-3 protein derived from triatoma infestans exhibiting activity to inhibit platelet aggregation

A protein derived from Triatoma infestans consisting of the amino acid sequence of following (d), (e) or (f):

• (d) an amino acid sequence represented by amino acids Nos. 1-164 shown in the sequence ID No. 1 of the sequence listing,
• (e) an amino acid sequence in which a part of amino acid sequence (d) is deleted, substituted, or another amino acid sequence is added to the amino acid sequence (d), the amino acid sequence (e) exhibiting activity to inhibit platelet aggregation;
• or
• (f) an amino acid sequence exhibiting homology 95% or more with the amino acid sequence (d), the amino acid sequence (f) exhibiting activity to inhibit platelet aggregation.

A gene derived from Triatoma infestans consisting of the base sequence of following (g), (h), (i) or (j):

• (g) a base sequence represented by base Nos. 1-695 shown in the sequence ID No. 2 of the sequence listing,
• (h) a base sequence in which a part of base sequence (g) is deleted, substituted or added, or another base sequence is added to the base sequence (g), the base sequence (h) encoding a protein exhibiting activity to inhibit platelet aggregation,
• (i) a base sequence exhibiting homology 95% or more with the base sequence (g), the base sequence (i) encoding a protein exhibiting activity to inhibit platelet aggregation;
• or
• (j) a base sequence that hybridizes with the base sequence (g), the base sequence (j) encoding a protein exhibiting activity to inhibit platelet aggregation.
