CEP1 — Asparagus officinalis

Summary

A4U43_C02F9140 (CEP1) in asparagus (Asparagus officinalis) on chromosome 2 encodes a cysteine proteinase of the papain-like C1A peptidase family, with thiol endopeptidase activity and proteinase-activated receptor binding. It is associated with proteolysis and NO storage, and localises to the vacuole, protein storage vacuole, lysosome, aleurone body, cytoplasmic vesicle, and ER lumen. Studies of related genes in other species link the family to seed storage protein processing and pollen allergenicity.
