CEP1 — Asparagus officinalis

Summary

A4U43_C05F16470 (CEP1) in asparagus (Asparagus officinalis) encodes a peptidase C1A papain C-terminal domain-containing protein with cysteine-type peptidase activity and thiol endopeptidase activity. The gene is associated with proteolysis, leaf senescence, programmed cell death involved in cell development, and responses to abscisic acid, ethylene, and gibberellin. It is also linked to flower and pollen development, cell differentiation, and NO storage. The encoded protein localises to the senescence-associated vacuole, lysosome, cytoplasmic vesicle, ER lumen, vacuole, and aleurone body. Studies of related genes in other species connect the family to similar proteolytic and senescence-related processes.
