CP1 — Brassica oleracea var. botrytis

Summary

BoCP1 (CP1, RDL1) on cauliflower chromosome 3 encodes a papain-like cysteine peptidase, belonging to the peptidase C1A family and containing a proteinase inhibitor I29 domain. The gene is associated with cysteine-type peptidase activity and proteinase-activated receptor binding, and its product localises to the vacuole, lysosome, protein storage vacuole, ER lumen, and extracellular space. BoCP1 is associated with proteolysis, response to red light and gibberellin, pollen and flower development, and cell differentiation. It has been linked to salt tolerance, seed germination, OPDA metabolism, and stress response. Related genes in other species link the family to seed dormancy and seed growth and development traits.
