PR5 — Cucumis sativus

Summary

CsPR5 (CSA_1G042760) on cucumber chromosome 1 encodes a thaumatin-like protein with glucan endo-1,3-beta-D-glucosidase activity and IgE binding capacity. It is associated with systemic acquired resistance, defence response to fungi, and killing of cells of other organisms, as well as response to abscisic acid. The protein localises to the apoplast and extracellular space. Related genes in other species link the family to glucan endo-1,3-beta-glucosidase activity (EC 3.2.1.39).
