HSP70 — Capsicum annuum

Summary

CaHSP70 (T459_19283) on pepper chromosome 7 encodes a heat shock 70 kDa protein 17, a chaperone with ATP hydrolase activity, ATP binding, adenyl-nucleotide exchange factor activity, and heat shock protein binding. It is associated with protein refolding, the ERAD pathway, the unfolded protein response, stress responses including heat and virus, virus-induced PTGS, cell death, pollen tube growth, ABA signaling, signal transduction, and defense responses. The gene has been linked to fruit length, photosynthetic rate, plant height, and thermotolerance, as well as heat, wound, abiotic, and radiation stress responses. It localizes to the ER lumen and chaperone complex, chloroplast membrane, cytosol, Golgi, vacuole, and secretory vesicles. Studies of related genes in other species connect the family to heat and drought tolerance.
