Insulin biosynthesis pathway
Nettetof proinsulin, including segments corresponding to the insulin B-chain, C-peptide, and insulin A-chain (Figure 1). Preproinsulin biosynthesis is initiated in the cytosol. As a first step in insulin biosynthesis, newly synthesized preproinsulin must be guided by its signal peptide to the ER for translocation [19, 20].
