CCP1 — Cucumis sativus

Summary

CSA_2G249900, also known as CCP1, on cucumber chromosome 2 encodes a cysteine protease belonging to the papain-like cysteine peptidase family. The gene product is associated with cysteine-type endopeptidase activator activity involved in apoptotic processes, feruloyl-CoA hydratase/lyase activity, and protein homodimerization. CCP1 is linked to several biological processes including proteolysis, immune system processes, autolysis, cold acclimation, flower and pollen development, and vanillin and phenylpropanoid anabolism. The protein localizes to the vacuole, lytic vacuole, and phenyloplast. Additionally, CCP1 is associated with oxidative stress response. Studies of related genes in other species link the CCP1 family to cysteine proteinase activity and the enzyme classes EC 3.4.22.16 and EC 4.1.2.65.
