In L-cells of the lower intestine and colon the proprotein convertase subtilisin/kexin type 1 (or PCSK1/PC1) cleaves after single or double basic amino acids to liberate glicentin (amino acids 21-89 in proglucagon), oxyntomodulin (amino acids 53-89 in proglucagon), GLP-1 (amino acids 92-128 in proglucagon), and GLP-2 (amino acids 146-178 in proglucagon) (see UniProt P01275)
