The receptor for insulin-like peptide 5 (INSL5), RXFP4, is a potential pharma target for treating human conditions such as constipation, anorexia, and obesity. However, since INSL5 has a complex structure of two chains and three disulfide bonds, its synthesis has proven to be extremely difficult via either chemical or recombinant approaches. Previous studies led to the engineering of a high yielding simplified INSL5 analog, named analog 13 (A13), which retains native INSL5-like activity. The focus of this study is to further simplify the structure of A13 by truncating the N-terminal residues of the B-chain. We have found that the first six residues at the N-terminus of A13 are not important ..View full abstract
