HSP70 — Brachypodium distachyon

Summary

BdHSP71.1 (BRADI_1G66590V3, HSP70) on chromosome 1 of Brachypodium distachyon encodes a heat shock 70 family protein with ATP-dependent protein folding chaperone activity, ATP hydrolase activity, and heat shock protein binding. It is associated with protein refolding, the ERAD pathway, the ER unfolded protein response, heat acclimation, response to heat and stress, auxin transport and signaling, amino acid membrane transport, and virus-induced post-transcriptional gene silencing. The protein localises to the ER chaperone complex, ER lumen, cytoplasm, nucleus, chloroplast membrane, tonoplast, and axonemal central pair projection. Related genes in other species link the family to salt stress response, ABA response, and traits including spikelet number, heat and drought tolerance, anthesis time, and abscisic acid sensitivity.
