HSP70 — Asparagus officinalis

Summary

A4U43_C03F21600, the HSP70 gene on asparagus (Asparagus officinalis) chromosome 3, encodes a heat shock protein 70 family chaperone with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. The gene is associated with protein refolding, the ERAD pathway, the unfolded protein response, and response to heat, stress, and virus. It has also been connected to progesterone anabolism, steroidogenesis, lipid metabolism, homeostasis, memory, and pollen tube growth. The encoded protein localises to the cytoplasm, nucleus, membrane, chloroplast membrane, ER lumen, ER chaperone complex, and axonemal central pair projection. Studies of related genes in other species link the HSP70 family to ATPase and peptide-binding domains.
