HSP22 — Cucumis sativus

Summary

CsHSP22 (CSA_7G072770) on cucumber chromosome 7 encodes a small heat shock protein (HSP20 family) with chaperone activity, annotated as a protein folding chaperone that binds identical proteins and localizes to the cytoplasm, ER lumen, and macromolecular complexes. The gene is associated with responses to heat, hydrogen peroxide, salinity, and defense, as well as protein folding, stabilization, and oligomerization. It is also linked to fruit ripening and angiogenesis. Related genes in other species are linked to sugar content, though this is not established for cucumber.
