PROBLEM TO BE SOLVED: To provide a DNA construct enabling inexpensive production of a target protein in Escherichia coli and further, being free from defect of conventional technique. SOLUTION: The DNA construct is composed of a nucleic acid sequence encoding a signal peptide, a gene encoding a carrier protein functionally bound to the nucleic acid sequence and a gene encoding a target protein bound through a gene encoding a sequence S which is cleavable with the above gene and enables the inexpensive production of the target protein in Escherichia coli. In the DNA construct, the gene encoding the carrier protein is a spy gene derived from Escherichia coli. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To provide an artificial protein having biological activity for use in pharmaceuticals. SOLUTION: Provided is a polypeptide which is coupled to albumin or its variant and contains an active moiety derived from a therapeutically active polypeptide. The active moiety is a polypeptide having a whole peptide structure or a therapeutically active structure derived from the whole peptide structure by structural modification (mutation, substitution, addition and/or deletion of at least one residue).

摘要:
A soluble fusion protein (I) comprising a human protein (II), or part of it, that is not of the immunoglobulin (Ig) family and different parts (III) of Ig molecules of any subclass, is new. An independent claim is also included for a method for preparing (I) by introducing a DNA that encodes it into a mammalian cell expression system, expressing (I), and purification by affinity chromatography through the Ig component. ACTIVITY : Hemostatic; Immunosuppressive; Antiallergic; Antianemic; Anticoagulant; Thrombolytic. No details of tests for these activities are given. MECHANISM OF ACTION : Protein substitution or inhibition.
摘要:
PROBLEM TO BE SOLVED: To produce a homogeneous protein-containing composition by selectively bonding a water-soluble polymer to the N terminals of a protein. SOLUTION: What is provided is a method for producing a stable protein-containing composition containing a substantially homogeneous monopolymer/protein conjugate by selectively modifying the α-amino acids at the N-terminals of a protein with a water-soluble polymer such as dextran, poly(N-vinylpyrrolidone), or polyethylene glycol by using reductive alkylation using a reducing agent such as sodium borohydride or sodium cyanoborohydride.
