HSP70 — Asparagus officinalis

Summary

A4U43_C01F1940, also known as HSP70, encodes an uncharacterized protein with an Hsp_70_fam domain and ATPase_NBD domain, with ATP hydrolase activity and ATP binding, functioning as a protein folding chaperone that binds heat shock proteins. In asparagus (Asparagus officinalis) on chromosome 1, this gene is associated with the unfolded protein response, the ERAD pathway, and protein refolding in the endoplasmic reticulum. It is linked to heat response, pollen development, pollen germination, and pollen tube growth, as well as steroidogenesis, progesterone anabolism, lipid metabolism, and homeostasis. The encoded protein localises to the ER lumen, chloroplast stroma, tonoplast, cytoplasm, nucleus, and membrane. Studies of related genes in other species link the family to chaperone functions in the ER.
