HSP22 — Pisum sativum

Summary

PsHSP22 (PSAT6G112880) on garden pea chromosome 6LG2 encodes a small heat shock protein (HSP20 family) with an A-crystallin/Hsp20 domain and chaperone activity. It is associated with protein folding, stabilization, and oligomerization, as well as energy homeostasis, embryogenesis, seed development, and responses to heat, hydrogen peroxide, hypoxia, and salinity. The protein localizes to the cytoplasm, ER lumen, and macromolecular complexes. Phenotype associations link PsHSP22 to heat tolerance and heat acclimation. Studies of related genes in other species connect the HSP22 family to seed protein content, germination rate, seed maturation, chlorophyll content, and high temperature stress response.
