HSP70 — Brachypodium distachyon

Summary

BRADI_1G66550V3 (HSP70) on chromosome 1 of Brachypodium distachyon encodes an uncharacterized protein with ATP-dependent protein folding chaperone activity, ATP hydrolase activity, heat shock protein binding, and ATP binding, belonging to the Hsp70 family. The gene is associated with protein folding in the ER, the ERAD pathway, erUPR, heat acclimation, response to heat, response to stress, auxin transport, auxin signaling, basipetal auxin transport, auxin polar transport, pollen tube growth, response to virus, virus-induced PTGS, amino acid membrane transport, membrane transport, and protein refolding. Localization evidence connects the product to the ER chaperone complex, ER lumen, chloroplast membrane, tonoplast, membrane, cytoplasm, and nucleus. The gene is also associated with spikelet number. Studies of related genes in other species link the family to similar chaperone functions.
