Abstract

A fusion protein is provided, comprising i) a biologically active polypeptide; and ii) a half-life extending polypeptide moiety comprising 2-80 units independently selected the amino acid sequences according to SEQ ID NO: 1: X1-X2-X3-X4-X5-X6-D-X8-X9-X10-X11 (SEQ ID NO: 1) in which, independently: X1 is P or absent; X2 is V or absent; X3 is P or T; X4 is P or T; X5 is T or V; X6 is D, G or T; X8 is A, Q or S; X9 is E, G or K; X10 is A, E P or T; and X11 is A, P or T. The half-life extending polypeptide moiety has a generally unfolded conformation and provides a fusion protein with a large hydrodynamic radius that may avoid renal clearance. As a result, the biological half-life of the fusion protein is increased and the biological effect of the biologically active polypeptide may thus be prolonged.
