HSP70 — Brachypodium distachyon

Summary

BRADI_1G66561V3 (HSP70) on chromosome 1 of Brachypodium distachyon encodes a heat shock protein 70, an ATP-dependent protein folding chaperone with ATP hydrolase and heat shock protein binding activities. The gene is associated with protein folding in the endoplasmic reticulum, the ERAD pathway, the ER unfolded protein response, and protein refolding. It is associated with heat acclimation, response to heat, response to stress, and response to virus, as well as auxin transport, basipetal auxin polar transport, auxin signaling, amino acid membrane transport, and virus-induced post-transcriptional gene silencing. The product localises to the ER lumen and chaperone complex, cytoplasm, nucleus, membrane, tonoplast, and chloroplast membrane. Studies of related genes in rice link the family to spikelet number.
