CEP1 — Asparagus officinalis

Summary

A4U43_C03F24610, designated CEP1 in asparagus (Asparagus officinalis) on chromosome 3, encodes a peptidase C1A papain C-terminal domain-containing protein with thiol endopeptidase and cysteine-type peptidase activity. The gene is associated with proteolysis, cell differentiation, flower and pollen development, and NO storage. Its product localises to the vacuole, lysosome, protein storage vacuole, aleurone body, cytoplasmic vesicle, and ER lumen. Studies of related genes in other species, including low-temperature-induced cysteine proteinases, link the family to stress responses and developmental processes.
