HSP70 — Asparagus officinalis

Summary

A4U43_C06F4580 (HSP70) on asparagus chromosome 6 encodes a heat shock 70 kDa protein with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. It is associated with responses to heat, stress, and virus, as well as protein folding in the endoplasmic reticulum, the ERAD pathway, the ER unfolded protein response, protein refolding, steroidogenesis, progesterone anabolism, lipid metabolism, homeostasis, and memory. The protein localises to the cytoplasm, nucleus, membrane, tonoplast, chloroplast membrane, ER lumen, ER chaperone complex, and axonemal central pair projection. Studies of related genes in other species link the family to similar stress and protein-folding roles, though these associations are not yet established for this specific asparagus gene.
