Depiction of the current status of C9JFL3, currently annotated as “Proline, histidine and glycine-rich protein 1”. The protein is 83 amino acids long, but produces no useful fully tryptic peptides—only one that is too short and one that is too long. Yet, due to its high abundance in some samples, many miscleaved peptides are detected, easily providing the minimum evidence. The red bars indicate well detected peptides in PeptideAtlas. Multiple semitryptic peptides originate from the only cleavage site after the sixth amino acid. Multiple nontryptic peptides originate from the C terminus.
