PR5 — Cucumis sativus

Summary

CsPR5 (CSA_3G003990) on cucumber chromosome 3 encodes a thaumatin-like protein, a member of the osmotin/thaumatin-like superfamily, with glucan endo-1,3-beta-D-glucosidase activity and IgE binding capacity. The gene is associated with systemic acquired resistance, defense responses to fungi, and killing of cells of other organisms, as well as response to abscisic acid. The encoded protein localizes 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).
