Abstract:
1. An albumin fusion protein comprising a member selected from the group consisting of: (a) a Therapeutic protein X and albumin comprising the amino acid sequence of SEQ ID NO:18; (b) a Therapeutic protein X and a fragment or a variant of the amino acid sequence of SEQ ID NO:18, wherein said fragment or variant has albumin activity; (c) a Therapeutic protein X and a fragment or a variant of the amino acid sequence of SEQ ID NO:18, wherein said fragment or variant has albumin activity, and further wherein said albumin activity is the ability to prolong the shelf life of the Therapeutic protein X compared to the shelf-life of the Therapeutic protein X in an unfused state; (d) a Therapeutic protein X and a fragment or a variant of the amino acid sequence of SEQ ID NO:18, wherein said fragment or variant has albumin activity, and further wherein the fragment or variant comprises the amino acid sequence of amino acids 1-387 of SEQ ID NO:18; (e) a fragment or variant of a Therapeutic protein X and albumin comprising the amino acid sequence of SEQ ID NO:18, wherein said fragment or variant has a biological activity of the Therapeutic protein X; (f) a Therapeutic protein X, or fragment or variant thereof, and albumin, or fragment or variant thereof, of (a) to (e), wherein the Therapeutic protein X, or fragment or variant thereof, is fused to the N-terminus of albumin, or the N-terminus of the fragment or variant of albumin; (g) a Therapeutic protein X, or fragment or variant thereof, and albumin, or fragment or variant thereof, of (a) to (e), wherein the Therapeutic protein X, or fragment or variant thereof, is fused to the C-terminus of albumin, or the C-terminus of the fragment or variant of albumin; (h) a Therapeutic protein X, or fragment or variant thereof, and albumin, or fragment or variant thereof, of (a) to (e), wherein the Therapeutic protein X, or fragment or variant thereof, is fused to the N-terminus and C-terminus of albumin, or the N-terminus and the C-terminus of the fragment or variant of albumin; (i) a Therapeutic protein X, or fragment or variant thereof, and albumin, or fragment or variant thereof, of (a) to (e), which comprises a first Therapeutic protein X, or fragment or variant thereof, and a second Therapeutic protein X, or fragment or variant thereof, wherein said first Therapeutic protein X, or fragment or variant thereof, is different from said second Therapeutic protein X, or fragment or variant thereof; (j) a Therapeutic protein X, or fragment or variant thereof, and albumin, or fragment or variant thereof, of (a) to (i), wherein the Therapeutic protein X, or fragment or variant thereof, is separated from the albumin or the fragment or variant of albumin by a linker; and (k) a Therapeutic protein X, or fragment or variant thereof, and albumin, or fragment or variant thereof, of (a) to (j), wherein the albumin fusion protein has the following formula:
