Early placenta insulin-like peptide is a protein that in humans is encoded by the INSL4 gene.INSL4 encodes the insulin-like 4 protein a member of the insulin superfamily. INSL4 encodes a precursor that undergoes post-translational cleavage to produce 3 polypeptide chains A-C that form tertiary structures composed of either all three chains or just the A and B chains. Expression of INSL4 products occurs within the early placental cytotrophoblast and syncytiotrophoblast.
