HSP70 — Camelina sativa

Summary

CsHSP70-16 (CSA03G015320) on Camelina sativa chromosome 3 encodes a heat shock 70 kDa protein family member with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone functions. It is associated with protein folding in the endoplasmic reticulum, the ER unfolded protein response, the ERAD pathway, protein refolding, the MAPK cascade, signal transduction, and responses to stress, heat, and salt. The gene is linked to regulation of wax anabolism, seed setting rate, flower opening, and heat stress tolerance, including sepal heat stress response. It localizes to the ER lumen, ER chaperone complex, cytosol, cytoplasm, nucleus, membrane, tonoplast, axonemal central pair projection, and mediator complex. Studies of related genes in other species connect the family to spikelet fertility and altered wax profiles.
