GLP-2 is created by specific post-translational proteolytic cleavage of proglucagon in a process that also liberates the related glucagon-like peptide-1 (GLP-1).
GLP-2 se formira putem specifičnog posttranslacionog proteolitičkog presecanja proglukagona u procesu kojim se takođe formira srodni glukagonu sličan peptid-1 (GLP-1).
