Post-translational modificationi

Extensively processed in glucagonoma tissue by limited proteolysis at conserved basic residues. Alternative processing are seen in different tissues. The proglucagon-converting enzymes present in transformed alpha-cells are likely candidates to be involved in tissue-specific processing.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
