CP1 — Brassica oleracea var. botrytis

Summary

BoCP1 (CP1, RDL1) on cauliflower chromosome 1 encodes a papain-like cysteine peptidase belonging to the peptidase C1A family, with cysteine-type peptidase activity and proteinase-activated receptor binding. This gene is associated with proteolysis, response to red light and gibberellin, pollen and flower development, and cell differentiation. Its product localises to the lysosome, vacuole, protein storage vacuole, cytoplasmic vesicle, ER lumen, and extracellular space. BoCP1 is linked to salt tolerance, seed germination, OPDA metabolism, and stress response. Studies of related genes in other species connect the family to seed dormancy and seed growth and development traits.
