CEP1 — Asparagus officinalis

Summary

A4U43_C01F21520, designated AoCEP1 on asparagus chromosome 1, encodes a peptidase C1A papain C-terminal domain-containing protein with thiol endopeptidase and cysteine-type peptidase activity. The gene is associated with proteolysis, programmed cell death involved in cell development, leaf senescence, and responses to the hormones gibberellin, ethylene, and abscisic acid. It has also been connected to flower and pollen development, cell differentiation, and NO storage. The encoded protein localises to the senescence-associated vacuole, protein storage vacuole, lysosome, aleurone body, cytoplasmic vesicle, and ER lumen. Related genes in other species link the family to similar senescence and developmental processes.
