Abstract

The present invention provides a method for effective extracellular secretion of a target protein, by preparing a fusion protein connecting LARD3 to the target protein and having pI lowered by adjusting the overall charge of target protein, and by using ABC transporter of a bacterial type 1 secretion system (T1SS). The method can allows a protein be produced at a large amount simply and effectively without a separate purification process.
