CEP1 — Asparagus officinalis

Summary

A4U43_C03F31850 (CEP1) in asparagus (Asparagus officinalis) on chromosome 3 encodes a granulins domain-containing protein belonging to the papain-like cysteine peptidase family, with thiol endopeptidase activity and cysteine-type peptidase activity. The gene is associated with proteolysis, cell differentiation, flower development, pollen development, and NO storage. Its product localises to the vacuole, lysosome, protein storage vacuole, cytoplasmic vesicle, and ER lumen. Studies of related genes in other species link the family to low-temperature-induced cysteine proteinases and cysteine proteinase COT44, though these associations are not established for this asparagus gene.
