Albumin fusion proteins
First Claim
1. An albumin fusion protein comprising a calcitonin polypeptide fused to an albumin polypeptide, wherein said calcitonin polypeptide is selected from:
- (a) a full-length calcitonin; and
(b) a mature calcitonin;
and wherein said albumin polypeptide is selected from;
(i) a full-length albumin;
(ii) a mature albumin;
(iii) a fragment of albumin;
(iv) a polypeptide consisting of an amino acid sequence at least 95% identical to mature albumin (SEQ ID NO;
18);
(v) amino acids 1 to 585 of SEQ ID NO;
18; and
(vi) amino acids 1 to 387 of SEQ ID NO;
18;
and further wherein the albumin polypeptide has the ability to prolong the serum half-life of the fused calcitonin polypeptide compared to the unfused calcitonin polypeptide.
