HSP70 — Asparagus officinalis

Summary

A4U43_C07F17760, designated HSP70 on asparagus chromosome 7, encodes a heat shock 70 family protein with an Hsp_70_fam domain and ATPase_NBD. The product possesses ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. It is associated with protein folding and refolding, the ERAD pathway, the ER unfolded protein response, response to heat and general stress, homeostasis, lipid metabolism, steroidogenesis, and progesterone anabolism. The protein has been linked to memory. It localises to the ER chaperone complex and ER lumen, as well as chloroplast stroma, mitochondria, cytoplasm, nucleus, and membrane. Studies of related genes in other species link this gene family to similar chaperone and stress-response roles.
