PRP1 — Cucumis sativus

Summary

CSA_2G176690, designated PRP1 on cucumber chromosome 2, encodes a protein of unknown molecular function. The gene is annotated to the biological processes of systemic acquired resistance and homeostasis, linking it to plant defence and internal balance. Studies of related genes in other species associate the family with stress responses and developmental regulation, though these connections are not yet established in cucumber. PRP1 is also linked to the uncharacterised protein KGN61606 and shares sequence similarity with several predicted proteins from melon and other cucurbits, suggesting a conserved role within the family. No enzyme class or molecular function has been assigned, so the precise biochemical activity of the PRP1 product remains unknown.
