Annotation of the precursor peptides of catshark preproinsulin (A) and preproglucagon (B). Signal peptides (amino acids 1–24 and 1–20 respectively) are underlined and basic amino acid cleavage sites are lowercase. Glucagon-like peptides (GLP) 1a and 1b are annotated based on similarity to the duplicated GLP1 peptides in the unpublished Squalus acanthias and Hydrolagus colliei proglucagon sequences available on Genbank (accession numbers AAS57653 and AAS57654). An oxyntomodulin-like peptide has been purified from H. colliei and corresponds to amino acids 47–82 in the catshark preproglucagon.
