Abstract: PURPOSE: A method for improving soluble expression of a target protein is provided to prevent insoluble precipitation of a recombinant protein and to improve recombinant protein secretion. CONSTITUTION: An expression vector for improving soluble expression and secretion of an active protein in which a membrane potential domain is folded contains: a promoter; and a gene construct which is operatively linked to the promoter and contains a polynucleotide encoding a leader polypeptide. A method for improving soluble expression and secretion of the active protein comprises: a step of designing a polynucleotide encoding a polypeptide with pI value of N-terminal to 2.00-6.00 and hydrophilic value to 1.00-2.00; a step of preparing a gene construct comprising the polynucleotide and a polynucleotide encoding the active protein; a step of operatively inserting the gene construct into an expression vector to prepare a recombinant expression vector; a step of transducing the recombinant expression vector to a host cell to form a transformant; and a step of culturing the transformant.
