HSP70 — Camelina sativa

Summary

CsHSP91 (CSA07G059930, also known as HSP70) on Camelina sativa chromosome 7 encodes a member of the Hsp70 family, an ATP-dependent protein folding chaperone with ATP hydrolase and heat shock protein binding activities. The gene is associated with the endoplasmic reticulum unfolded protein response (erUPR), the ERAD pathway, protein refolding, the MAPK cascade, and responses to stress, heat, salt, and virus. It is linked to oxidative protein folding and protein folding processes. The encoded protein localises to the ER chaperone complex, ER lumen, chloroplast membrane, plastid, plasmodesma, and other compartments. Studies of related genes in other species link the family to heat tolerance, virus resistance, stomatal closure, and plant growth, and the family has been connected to leaf shape and stomatal complex closure time.
