Periplasmic protein without signal peptide

WebA commonly encountered problem is that the signal peptide influences the synthesis and secretion of the recombinant protein in an unpredictable manner. A molecular understanding of this phenomenon is highly sought after, as it could lead to improved methods for producing recombinant proteins in bacterial cell factories. WebProvided is a recombinant protein, which contains a nerve growth factor (NGF) protein variant and a heterologous signal peptide linked to the NGF protein variant. Further provided are a combination containing an mRNA encoding the recombinant protein and a delivery vector, and the use thereof in the treatment of toxic/hereditary/metabolic peripheral …
