HSP70 — Camelina sativa

Summary

CsHSP91 (CSA07G059920, also known as HSP70) on Camelina sativa chromosome 7 encodes an ATP-dependent protein folding chaperone with ATP hydrolase activity, heat shock protein binding, and disulphide bond formation functions, belonging to the Hsp70 family and containing an ATPase nucleotide-binding domain. This gene is associated with the endoplasmic reticulum unfolded protein response (ER UPR), the ERAD pathway, protein refolding, the MAPK cascade, signal transduction, and responses to stress, heat, salt, and viruses. It is linked to protein folding and oxidative protein folding phenotypes. The encoded protein localizes to the ER lumen, ER chaperone complex, chloroplast membrane, plastid, plasmodesma, plant-type cell wall, vacuole, and secretory vesicle. Related genes in other species link the family to heat tolerance, stomatal closure, virus resistance, and plant growth.
