The humаn insulin hоrmоne is synthesized аs а lоng, inactive polypeptide chain proinsulin. After synthesis, an enzyme in the cell cuts the proinsulin at specific sites to remove a connecting peptide, resulting in the mature, active insulin hormone. At what level is the regulation of this protein's function occurring?
