HSP70B — Brassica oleracea

Summary

BoHSP70B, encoded by BOLC102_C08P026940.1 on cabbage chromosome 8, is a member of the Hsp70 family and possesses ATP hydrolase activity, ATP binding, protein binding, and heat shock protein binding, acting as a protein folding chaperone. It is associated with protein folding in the endoplasmic reticulum, the ER unfolded protein response, ERAD pathway, cytosol-to-ER transport, and protein refolding. The gene is linked to responses to heat, stress, and virus, as well as systemic acquired resistance, lignin anabolism, calcium signaling, lateral root development, embryogenesis, mitotic cell cycle, cell division, and vesicle transport. It localizes to the ER lumen, chloroplast membranes, tonoplast, and plant-type cell wall. Associations include reproductive growth time, cell cycle and root development traits, root thickness, abiotic stress and heat tolerance, and seed germination under abiotic stress.
